Questions tagged [analog-switch]
An electrical component which performs a similar function as a mechanical relay (conducts an analog or digital signal when on but does not conduct when off). Unlike a mechanical relay, however, it has no moving parts, and it may or may not provide galvanic isolation between the control signal and the switching terminals.

Switching circuit with logic 3.3V control on p-channel JFET
The task is to derive sinewave (of higher frequency) chopped by step-function (also periodic but of lower frequency, i.e. several periods of sine wave are placed in that pulse). So I have a sinewave ...

Simplify one-time switch made using a flip flop
I'm trying to make a one-time, "turn-on-once" switch. I've made a simpler design before, but I seem to have lost it.
So basically, when the comparator is pulled to high, the switch turns on ...
