Abstract :
In complementary input differential pair circuits, the topology CMOS uses both an nMOS differential pair and a pMOS differential pair connected in parallel however, it produces variations in the transconductance over the input common mode range. To avoid the problem of transconductance variations, a new structure, consists of two op-amps one n-type and the other p-type controlled by a digital control system, is proposed. In this paper we purpose a solution of the instability problem of a voltage driver in 40 mV, and to improve the stability we subtract a constant current through the current mirror added to the driver.
