In the figure we have an IF amplifier step using a MOSFET. The circuit was found in a 1980s documentation, intended for FM receivers of the time.
In the figure we have the way to use a zener instead of a filter capacitor. The zener can have the...
ST Microelectronics has, in its line of low voltage drop linear regulators, the KD1084xx (fixed) and...
This remote control for resistive loads using a triac appears elsewhere on this site. The circuit...
