Abstract
A method provided herein is adapted to a sense amplifier having a first cross-coupled latch and a second cross-coupled latch, each of which includes a first pair of transistors and a pair of coupling capacitors coupled to respective gate terminals of the first pair of transistors. The method includes, during a first phase, charging the pair of coupling capacitors of a first pair of transistors at a first cross-coupled latch to achieve zeroing and providing a first set of input voltages to a second cross-coupled latch, and, during a second phase following the first phase, discharging the pair of coupling capacitors to cancel a mismatch between the first pair of transistors and comparing the first set of input voltages provided to the second cross-coupled latch to generate a first set of output voltages.
