Abstract :
A two-stage low voltage operational amplifier for operation at plusmn0.4 V is proposed. The amplifier incorporates a low voltage current mirror designed using standard floating gate MOSFETs. The proposed op amp possesses a 49 dB open-loop gain, a high bandwidth of 698 kHz, 42deg phase margin and consumes only 28.6 muW. The operation of the proposed current mirror and op amp has been confirmed by PSPICE simulations, using 0.13 mum CMOS technology.
