Operational amplifier applications

Operational amplifiers (Op Amp) have been in use for quite a long a long time now in the field of electronics and electrical engineering. A basic Op Amp has got three connections consisting of 1 output and 2 inputs. For definition purposes the two input terminals are called inverting and non-inverting inputs (Huijsing, 2011). Huijsing (2011) adds that it has been found and proven that when the voltage at both points of the inputs is the same, there will be no output on the other side. The image below

Abstract - Operational amplifiers (Op-Amps) are basic building blocks of a wide range of analog and mixed signal systems. Basically, Op-Amps are voltage amplifiers used for achieving high gain by applying differential inputs. As CMOS technology is most suitable for realizing VLSI system, it leads to continues trend in scaling down the size of transistor. Hence, reduced power dissipation is one of the challenges in front of most of designers. However, Power dissipation can be reduced by reducing either
