Design of Op-Amp based Comparator

Ather Suhail

Abstract: Operational amplifier is a DC coupled electronic voltage amplifier having high gain, consisting of two input terminals viz. inverting input terminal and non-inverting input terminal and is capable to produce a single output potential at Vout terminal. This paper is based on op amp as a comparator. In this paper we preferentially go towards the design of op-amp as a comparator. Here we will discuss about its static and dynamic operations, the comparator as a main block design in the sigma delta comparator. The Op-amp as comparator in the design of this type amplifier low power and high speed. The CMOS design of circuit has been verify by using IDE simulator.
