Abstract
A power short pulse generator for generating a pulse on a rising edge and falling edge of an input signal according to the present invention comprises an input node for receiving the input signal and an output node for supplying an output signal. A first pulldown circuit and a second pulldown circuit are connected in series between the output node and a first supply voltage potential, the first pulldown circuit and the second pulldown circuit each having an input. A third pulldown circuit and a fourth pulldown circuit are connected in series between the output node and the first supply voltage potential, the third pulldown circuit and the fourth pulldown circuit each having an input. A pullup circuit is connected between the output node and a second supply voltage potential, the pullup circuit having an input. A leakage current circuit is connected between the output node and the second supply voltage potential. A feedback delay circuit has a feedback circuit input connected to the output node and a feedback circuit output connected to the input of the pullup circuit. A first input delay circuit is connected between the input node and the input of the first pulldown circuit and the second pulldown circuit. A second input delay circuit is connected between the input node and the input of the third pulldown circuit and the fourth pulldown circuit.
