Astable oscillator

Posted on Jul 25, 2012

Before power is applied, the input and output are at ground potential and capacitor C is discharged. On power-on, the output goes high (Vdd) and C charges through R until V is reached; the output then goes low (Vss). C is now discharged through R until Vn is reached. The output then goes high and charges C towards VP through R. Thus input A alternately swings between VP and Vn as the output goes high and low
