Low power comparator comparing differential signals

1. Field of the Invention A comparator comparing a differential input signal (represented by INM and INP single ended signals) with a differential reference signal (REFP and REFM) to generate a comparison result. The result may be amplified by a desired high amplification factor while consuming minimal electrical power. The comparator may contain two regenerative latches, with each latch containing two terminals. The INM, INP, REFP, and REFM are provided on the four terminals via respective switches. The first and second terminals of the first regenerative latch may respectively be connected to the first and second terminals of the second regenerative latch, with a switch in the path of each connection. The switches may be operated and the regenerative latches may be enabled for a short duration, to generate an amplified comparison result.
