Pulse generation with adjustable pulse width using current and voltage control

Abstract

The first inverter 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 first inverter to an input of the first inverter, thereby setting the first inverter in a linear mode. The adjustable current source is coupled to the negative-feedback circuit and is configured to load the first inverter, thereby modifying a duty cycle of the periodic wave produced by the first inverter. The second inverter is configured to invert the output of the first inverter, thereby generating the periodic square wave.
