In this paper, a new operational amplifier is presented that improves the specifications such as dc gain, common mode rejection ratio. To obtain these improvements, we have used the two important concepts of feedback and bulk amplification.

A CMOS circuit is proposed which takes multiple analog input currents and extracts minimum input current at the output. It is very fast and requires no subtraction from the constant current source. It exhibits O(N) complexity and uses only 4N MOS transistors where N is the number of system inputs. This circuit consumes very little power and very small area. The substrate bias affects the threshold voltage of transistors and improves performance of the structure.
