Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – ...

LDRs or Light Dependent Resistors are very useful especially in light/dark sensor circuits. Normally the resistance of an LDR is very high, sometimes as high as 1000 000 ohms, but when they are ...

In this installment of Circuit VR, we’ll look at a simple buck converter — that is a switching regulator that takes a higher voltage and ... the switch doesn’t have to be ... Block diagram-wise: ...

Bootstrap circuits are very common when NMOS (or NPN) devices are used on the high side of a switching circuit, ... A simple half-bridge driving illustrates the high-side NMOS driving problem.
