If you still need to generate a pulse for the analog switch IC, try something quieter, slower, with lower output drive, like 74HC or AHC, and put a 33R SMD resistor in the output to avoid any ringing. And put a decoupling cap on them!

Spletback to dc. The demodulator consists of a switch S 2 that is synchronously driven to S 1. An integrator then smooths the switch output and presents the final dc output. The circuit benefits from high overall dc gain and low baseband noise. The dc gain, being the product of the ac stage and the dc gain of the integrator, easily reaches an Splet09. dec. 2015 · It’s necessary because dumping the capacitor directly through the switch produces unwanted high-frequency voltage noise.
