Abstract :
A fully differential operational amplifier operating within a 2 V power supply range is presented. The amplifier was designed using 1.2 μm CMOS technology and uses a novel multi-regulation technique to provide a high open loop gain without degrading the open loop phase response. Fully differential techniques are employed so that the amplifier is able to operate over a larger input voltage range. The output voltage swing extends to be within 0.2 V of the lower and upper power supply rails
