We will now see how we can switch AC loads using Mosfet’s transiostors (using mosfet’s
This simple circuit generates stable square wave at differents frequencies, using from 3v to 12v
_An inverter is a circuit that converts dc voltage to ac voltage, The circuit uses
This is a high gain low signal preamplifier made by two small transistors bc549.Both transistors
This is a low current transformerless power supply for small applications. The capacitor C1 reduces
This easy circuit is a good amplifier for low audio signals such as electret microphone.
