Similarly, the capacitor charges from the spikes and discharges to maintain a steady voltage across it, ensuring that the spikes do not affect the IC supply. This is because the capacitor voltage does not change instantaneously and provides the supply to the IC. Adding a suitable capacitor across the supply compensates for the voltage drop.

It also negatively impacts the power integrity of your design. This makes it harder to differentiate between 1 and 0, closing your eye diagram. At the same time, these spikes bring the ground to a slight positive voltage, causing the value of what constitutes as low (state low) to increase. If there is a drop in the supply voltage, the value of what constitutes a high (state high) will decrease. The capacitor starts charging from the power supply until it reaches the supply voltage and holds that value. They filter out any spikes that occur and protect the different ICs in the circuit. Power supplies are not always stable due to non-ideal operating conditions and the output voltage can fluctuate or develop noise which can cause the circuit to misbehave or even fail.ĭecoupling capacitors are used in parallel to the power supply to decouple the incoming AC signals from the DC signals. Effectively place decoupling/coupling/bypass capacitors

To learn more about design reuse, see auto grouping of repetitive PCB design blocks. Circuits in these blocks could also be replicated in other designs requiring similar functions, promoting design reuse. For example, output from an LDR (light-dependent resistor) sensor needs to be converted to a voltage range that can be easily read by the microcontroller ADC. Some blocks may have signal conditioning circuits so that the output can be read easily by the data acquisition system.

Knowledge and understanding of the operation of each of these blocks are necessary. They also allow for a divide-and-conquer strategy where the diagram is broken down into different functional sections, each performing a specific task that can be implemented and tested in isolation. Block diagrams are crucial for successful electronic circuit design and act as a reference material for future circuit analysis. The next step is to build block diagrams that provide an overview of the circuit functioning and component groupings.

Operating temperature and frequency rangesĪll this should be done keeping in mind the available budget.

Your first step in designing an electronic circuit is to develop a detailed requirements specification that covers all aspects of circuit design including: Define specifications and build block diagrams
