Abstract
A pulse generation circuit delivers an output pulse whose width is tailored to the load. The pulse generation circuit comprises the following components. A drive circuit has an input coupled to receive a clock signal and an output coupled to drive a load. A comparator has an input coupled to the output of the drive circuit. Another input of the comparator is supplied by a reference voltage. A feedback circuit comprises logic gates and is coupled between the output of the comparator and the input of the drive circuit. The feedback circuit terminates a pulse output from the drive circuit when the pulse voltage output from the drive circuit exceeds the reference voltage. The reference voltage is higher than a voltage required to trigger the logic gates and a voltage required to drive the load. This ensures that the load is driven adequately over a wide range of load currents and capacitances. By setting the reference voltage between the voltage required to drive the load and the supply voltage, the pulse width is not excessive.
