Abstract
A microprocessor is implemented using sense amplifiers to replace CMOS logic circuits, in order to provide low voltage, high frequency switching. The input node of the sense amplifier is maintained at a voltage just above or just below their trip-point of one inverter in order to obtain high-speed switching. Bench mark tests have shown that a microprocessor operating at 2.7 volts may obtain a frequency of 20 MHz and while the same microprocessor may operate at 5.5 volts and 40 MHz.
