Abstract
An improved sense amplifier for receiving differential inputs and providing an output signal. A level shifting circuit for receiving differential inputs (IN and IN) is provided. A pre-amplification circuit that is coupled to the level shifting circuit provides gain to the differential outputs. A first inverter is coupled to the pre-amplification circuit and provides high voltage gain to the output signal. The first inverter includes a power port for receiving a power voltage signal and a ground port for receiving a ground signal. A second inverter that has a ground port and a power port is coupled to the pre-amplification circuit. The power port of the first and second inverters are coupled to the power voltage supply through a first transistor. Similarly, the ground port of the first and second inverters are coupled to the ground via a second transistor. The output of the second inverter is coupled to the gate of the first and second transistors and controls the first and second transistors.
