Abstract :
The work describes a self-isolated gain-enhanced sense amplifier (SGSA) for high-speed memory. A pair of incoming signals with large capacitive load can be self-isolated to the input nodes of the SGSA during the transient operation. The input nodes of the SGSA are then regenerated through the self-feedback control of the sense amplifier. Thus the gain is enhanced and the speed and driving capability is improved. The simulations using a 0.25 μm CMOS process parameters show that the SGSA has 10-77% speed improvement compared to the proposed sense amplifiers.
