Abstract
A sensing circuit capable of detecting very low current pulses of the order of 10's and 100's of micro amps. The sensing circuit comprises a common gate amplification stage capable of amplifying a sensed current, a comparison stage having as an input the amplified sensed current and a feedback stage capable of returning an output of the comparison stage to the common gate amplification stage.
