Pulse generation with adjustable pulse width using supply and amplitude variations

Abstract

The front-end inverting gate is configured to invert the periodic input signal, thereby generating a periodic wave. The negative-feedback circuit is configured to couple an output of the front-end inverting gate to an input of the front-end inverting gate, thereby setting the front-end inverting gate in a linear mode. The variable supply rail inverting gate is connected in series with the front-end inverting gate and is configured to generate the periodic square wave signal. The duty cycle control circuit is configured to supply an adjustable supply voltage to the variable supply rail inverting gate, thereby controlling a duty cycle of the periodic square wave signal.
