ABSTRACT:
A low-power, high-performance inverter circuit comprises first and second inverter circuit portions. The first portion comprises a first inverter, including a first pull-up element and a first pull-down element, for inverting an input signal, a first switching element connected between the first pull-down element and ground for switching the first inverter, and a first diode connected between the first pull-down element and ground in parallel with the first switching element. The second portion comprises a second inverter, including a second pull-up element and a second pull-down element, for inverting an input signal, a second switching element connected between the second pull-up element and a supply voltage terminal for switching the second inverter, and a second diode connected between the second pull-up element and the supply voltage terminal in parallel with the second switching element. An output of the first portion is connected to an input of the second portion.
