Abstract :
A CMOS realisation of a current operational amplifier operating under 3 V supply voltage is presented. The proposed implementation provides very high common-mode rejection. Results of HSPICE simulation show a high open loop current gain of 67 dB, a gain-bandwidth product of -100 MHz and a common-mode rejection ratio of 150 dB
