A while back, one of my devices failed the electromagnetic disturbances test. More specifically, there were problems with the conducted emissions on wired network ports in the frequency range from 150 kHz to 30 MHz. The device only passed for…
Backfeeding is a concept that is often discussed but not always fully understood. Backfeeding, in the context of electronics, refers to the flow of electricity in a direction opposite to the intended flow. This phenomenon primarily occurs over the signal…
In this blog post, we will explain how to design a circuit to directly monitor temperature using an NTC thermistor with an analog-to-digital (ADC) converter on any microcontroller like an Arduino or STM32. What is a NTC thermistor An NTC…
