Abstract
An ultra low power sense amplifier circuit for amplifying a low swing input signal to a full swing output signal is disclosed. In one aspect, the amplifier circuit includes a first amplifier stage for pre-amplifying the input signal to an intermediate signal on its internal nodes, a second amplifier stage for amplifying the intermediate signal to the output signal, and a control circuit for sequentially activating the first and second amplifier. The first amplifier has a capacitor for limiting energy consumption and two upsized PMOS transistors without NMOS transistors.
