Original Abstract Submitted

Aspects of the present disclosure provide a method for regulating an integration current of a sensing amplifier. The sensing amplifier includes a first input transistor and a second input transistor, wherein a source of the first input transistor and a source of the second input transistor are coupled to a source node. The method includes pulling a current from or sourcing the current to the source node, measuring the integration current, comparing the measured integration current with a reference signal, and adjusting the current pulled from or sourced to the source node based on the comparison.
