Design of low voltage low power high gain full swing operational amplifier
R Anil Kumar,  Komira Yakaiah,  Thummanapally Manusha
In this paper a design of conventional two stage CMOS operational amplifier was designed with all the transistors operated in sub threshold region, which allows low supply voltages with low power dissipation. When the transistors are operating in sub threshold region then there is an advantage of low power and low input bias current but there exist a problem in gain and full swing of the op-amp, the present approach overcomes this and maintains good tradeoff between gain, power consumption, and UGF with output swing ±Vdc. The proposed operational amplifier operates at ±450mv power supply with 1µAmp input bias current and the design is carried out in 180nM CMOS cadence analog virtuoso spectre simulator.
Keywords- CMOS OP-Amp, Full swing high gain Op-Amp, Operational-Amplifier, Sub threshold, 180nM.
