When building any electric device that will rely on electric signals, you will have to pay attention to the integrity of the generated signals. Signal integrity is given special attention when designing discrete semiconductor components. You don’t want to experience any kind of issues that are related to the generation and even transmission of signals from one semiconductor device to another.
While there are various ways of solving signal integrity, choosing the right design of a semiconductor is one of the solutions. A proper design should be able to address specific problems that are related to both analog and digital signals. The end-goal is to ensure that the signals don’t get distorted. Keep reading as we discuss the importance of signal integrity in discrete semiconductor design.
Basics of signal integrity
What is signal integrity and why is it important?
Signal integrity, which is always abbreviated as SI is a parameter that measures the quality of signals being generated and transmitted in electronic applications. In digital electronics, these electric signals which represent current and voltage are often represented by binary numbers. But in reality, the signals are analog in nature.
All types of electric signals, regardless of their nature or even source are subject to signal noise or distortion. The distortion is likely to lead to the loss of signals or low quality of signals. The integrity of signals may not be that bad if they are transmitted over a short distance. However, it can be a serious problem if the signals are intended to cover a long distance. It is impossible to rely on the signals that are of low integrity.
Signal integrity engineering is part of the discrete semiconductor development process. Its core role is to analyze semiconductor factors that are likely to affect the integrity of the signals. Of course semiconductor design of the focal points that affect signal integrity.
When should I worry about signal integrity in semiconductor design?
As we have already mentioned, it is technically impossible to build a discrete semiconductor that is completely 100% noise-proof. However, the purpose of the design is to ensure that ensure that the noise does not interfere with the functionality of a device. Another purpose of the design is to minimize the generation of excessive noise. There are numerous cases that make it necessary to focus on signal integrity when implementing discrete semiconductor design.
- When you want to get accurate impedance calculations and at the same time minimize reflection of signals.
- When the circuit or device is highly prone to signal loss through signal dispersion.
- When the application is at risk of crosstalk that is caused by fast switching of the digital signals.
- When the signals are prone to the undershoot and overshoot caused by the excessive inductance.
- When the application has a fiber weave which will cause signal loss
- When there is a possible loss of signals on the connection wires or comer wires due to their roughness.
- When the circuit is likely to be prone to the jitters due to the electric magnetic interference
- When the coupling of high-frequency signals in electric circuits is through parasites.
Why integrity is important when designing discrete semiconductors
We have just listed various situations in which signal integrity should be prioritized. Now let’s look at some of the key benefits of signal integrity in discrete semiconductor design.
For the best performance
Perhaps this should rank as one of the core reasons why signal integrity is among the key tenets of discrete semiconductor design. Whichever area of application you will be using the semiconductor component, you can be sure of the best performance only when the signals involved pass the integrity test.
Let’s say the semiconductor is used in data and communication applications. Signal integrity will guarantee high data speed and as well as minimum data loss. Also, the data being relayed from one end of the communication to another will be accurate.
Additionally, signal integrity reduces jitters, which are the changes in the signal timing. The overall result is predictable signal timing which results in the stability of the operation.
When it comes to data applications, the integrity of the signals used has a direct impact on the data integrity. It means that the data will be accurate and can be fully trusted. When do we say that the integrity of data has been preserved? First, if the signal relays all the data that was fed at the input stage to the output stage. This means that there was minimal data loss. Also, when the signal is devoid of noise or any other interference such as EMI.
Discrete semiconductors are widely used in power electronics where they execute different functions all of which are directly related to the electric signals. It is in such applications that the integrity of the power signals can come under close scrutiny. With the right design, it will be easy to achieve the integrity of the signals used. This will help in minimizing power loss in the system hence improving the energy efficiency of the devices and applications. Power efficiency due to high signal integrity also helps to improve the safety ratings of devices.
Signal integrity is something that discrete semiconductor designers and manufacturers should invest in. Before any semiconductor device is released to the market, it has to be tested whether it meets all the requirements to satisfy the integrity of the signals. The overall results of signal integrity are the performance and reliability of the system.
One way of ensuring that your discrete semiconductors meet the signal integrity is by buying from the best brands. By this, we are referring to the best manufacturers, suppliers, and distributors of discrete semiconductors. The easiest way of accessing them is by contacting discrete semiconductor sourcing agents. Using their experience and resources, they will be able to connect you to discrete semiconductor parts that are designed to meet the highest levels of signal integrity. At the end of it all you will experience robust performance on your electronic device.
