Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...

There are several applications in which pulses longer than the set width are to be detected, ignoring the other short pulses. We are familiar with the missing pulse detector circuit, which detects the ...

How to build a circuit that converts capacitance into a pulse train. Test results of the circuit design. The circuit in Figure 1 allows you to convert capacitance into a pulse train by using a ...

T his article is a follow-up to the one on SELF capacitance [1], and together, they cover the theories and design guides for the two most popular capacitive sensors, the projected and self capacitive ...
