Which Considerations Are Important For Analog PCB Design?

Analog PCB design guidelines are essential for a sound design for analog devices. There are many rules for both analog and digital circuit boards. The most notable considerations for this type of PCB are-

Compact Component Placement

A compact placement of analog components on the PCB surface is essential for having direct analog signals. It also helps to keep the digital and analog elements of the circuit separate from each other.

Watch this video to get a better idea:

Keep The Noisy Components Centered

It is necessary to place the noisy components at the center of the PCB design. It helps to avoid noise production during signal transmission. Besides, this placement allows the ground planes to absorb noise to a certain extent.

Isolation Of Analog And Digital Components

Both analog and digital components have a significant influence on each other due to noise. That’s why these elements require separation.

It is a fact that the noise of digital portions hampers the signal transmission of analog circuitry. So, you have to avoid placing high-speed and high-frequency digital signal traces along with the analog components.

Using Short Signals

In the case of data probation at a higher frequency range, impedance matching is a great challenge. Its deterioration causes reflection in analog signal traces, which is a significant reason for EMI.

You can avoid this situation by keeping the signal path direct and short as much as possible. Besides, you keep the PCB traces on a single layer. It helps reduce PCB vias and decreases the inductance of these PCB components.

Analog Grounding

You need to manage a dedicated ground plane for analog signals. It protects analog signals from noise and interference created by digital signal traces. It is especially mandatory for high-speed analog-digital circuits.

Providing A Smooth Return Path For Analog Signals

It is necessary to ensure a clear return path for analog signals. In most cases, designers obstruct the return path through vias, slots, cutouts, etc.

This kind of blockage produces noise that hampers the quality of signals. That’s why you should provide a smooth return path for analog and digital signals.

Reduction Of PCB Vias

It is not good to use PCB vias in the middle of the signal path of analog circuit boards. Excessive use of PCB vias makes all the analog circuitry offensive to each other. Such as-

• Supply bypass to signal
• Analog input to clock.

Avoid Impedance Discontinuity

You should avoid putting any impedance discontinuity at around 800 mils from analog-digital circuits. It is required to place the shunt capacitor close to this distance.

Besides, you need to consider the following subjects

• Reduce The Use Of Directional Couplers If Not Necessary
• Avoid overlap of power planes.
• Keep the ground bypass capacitors at the same plane.
• Avoid using unnecessary thermal relief in ground planes.

Analog PCB Design Considerations

How To Route Analog Signals In Analog PCB?

Routing means transmitting analog signals along an interconnect. It ensures minimum distortion at the receiver points of the analog circuit board interconnects. You have to follow some analog PCB design guidelines to route the analog signals properly. Such as-

Length Of The PCB Trace

The trace length of analog circuit boards needs to be short and direct to be compatible with high-frequency signals. Usually, long trace length is not worthwhile for high-power and high-frequency signal transmission systems.

Besides, you need to consider the critical signal length and pay attention to signal losses.

Impedance Control

Analog circuit boards need to maintain impedance matching at any cost. You can apply some reflection-less power transfer mechanism between the components to control the impedance per your demands.

Moreover, you can consider using some impedance matching networks on essential circuitries.

Analog Signal Routing In Analog PCB

Coplanar Routing

Coplanar PCB routing for analog signals allows you to isolate the analog and digital circuitry. But you don’t need to reduce the impedance. You can easily ensure impedance control in the case of violating 3W rules for the copper pours.

Effective Use Of PCB Vias

You should minimize the application of PCB vias in analog circuit board designs. Different types of vias cause a signal loss to the perimeter of the interconnects.

You need to keep only vias that radiate the analog signals strongly, like antennas. Layer transitions are also effective in some cases to reduce signal loss.

Design Of An Analog Digital Circuit Board

Which Factors Are Important For Analog PCB Layer Stackup?

Layer stacking is the most crucial thing after completing the design of an analog PCB. You need to pay close attention to the following factors to get the best output from the multilayer stackup.

Material Sourcing

Usually, FR4 and PTFE are the most used materials for analog circuit boards. You have to choose the suitable material for your project based on your requirements.

For example, FR4 materials are adequate for small frequency range and short routing paths. Besides, these elements are cost-effective for low and high-volume PCB applications.

On the contrary, PTFE ensures low loss during signal transmission. Low-loss PTFE materials will be the best option if you intend to apply long interconnects. But these materials cost a lot.

You can optimize your analog and mixed designs by using hybrid materials. You need to consult your manufacturer to apply high-quality materials during stackup.

Grounding

You need to ensure the smooth carrying of critical signals in analog circuit boards. That’s why proper grounding is mandatory. It is important to apply various grounds around the PCB traces. Besides, route your power rails concerning the analog interconnects of your multilayer stacks.

High-Frequency Power

A stable power supply is essential for keeping the analog circuit board functional at high frequencies. Besides, you need to consider its highest current carrying capacity while designing the layer stackup.

You can use a power plane instead of PCB rails on the internal layer., you can use a power plane. Then, placing a ground plane close to the power plane helps transmit high-frequency signals.

Analog Multilayer PCB Stackup

How To Separate Analog And Digital Grounds In PCB?

Analog signals are susceptible to noise, and digital signals are noisy. So, you need to separate their grounds in analog PCB design to reduce the noise and EMI (Electromagnetic Interference).

This isolation involves separating both power rails and ground returns. You can isolate them by placing the noise-sensitive parts in low-noise analog portions. Again, set the noisy components like digital logic, DC-DC Converter, relays, etc at digital sections. That’s how you can efficiently isolate the analog and digital ground PCB layout.

Component placement plays a vital role in the performance of analog PCBs in electronic applications. If you can ensure a tight placement of analog and digital components, you can keep the analog signals direct and short.

You can follow these guidelines mentioned below for optimum component placement.

• Place the analog and digital components in analog and digital sections of the circuit board, respectively.
• Place the noisy analog components in the middle of the circuit board.
• Keep the low-noise components at the perimeter of the PCB surface.

You can face some difficulties in dealing with unused operational and power amplifiers. If the power amplifiers run at high frequencies, there is a possibility of amplifier instability in the design.

You can track coupling back into the power amplifier input to solve this issue. You need to apply a field solver that interfaces to the analog circuit board layout.

Sometimes, some operational amplifiers remain unused, causing noise during the operation. That’s why you need to terminate these Op-Amps properly.

But how can you get relief from unused op-Amps?

• First, short the output that backs the inverting input in the case of a single power supply rail. It enables the output signal to follow the input and create negative feedback.
• Then, you need to connect a voltage divider with the ground pin and non-inverting input. It helps to set the input voltage at the middle range.
