Abstract
A circuit and method for speed and stability enhancement for a sense amplifier comprises an offset current apparatus and a discharge current apparatus connected to a data node on one side of a transmission transistor that has another side with a sense node connected to a charge current apparatus and a leakage current apparatus with the leakage current mirrored from the offset current. The offset current ensures the transmission transistor not shut down and the voltage on the data node below a specific level, thereby enhancing the speed of the sense amplifier. The leakage current enhances the stability of the sense amplifier. Mirroring the leakage current from the offset current results good control of the operation and performance of the sense amplifier.
