DESIGN OF A SQUAT POWER OPERATIONAL AMPLIFIER BY FOLDED CASCADE ARCHITECTURE

The objective of this paper is to implement the full custom design of low voltage and low power operational amplifier which operates at high frequency, which is applicable for the Micro Electronics and Telecommunications. In order to design the low power operational amplifier, certain compensation techniques are used. At the input side, transconductance removal technique was used by using the complimentary differential pair. At the output side, to achieve high swing output, class AB output stage was used. The operational amplifier is used to implement the ADC circuit. This paper will briefly outline the performance of operational amplifier operating at lower supply voltages. In this paper each individual parameter is measured. Simulations of the entire paper are implemented in CADENCE software.
