Abstract: Instrumentation amplifiers (IA) play a crucial role wherever small differential voltages need to be amplified precisely in the occurrence of a any voltage at the input. It must therefore attribute high input-impedance, small input-referred noise and offset voltage, large differential-voltage gain without feedback and significantly cast-off deviations on power-supply and common mode voltages. In this paper efficient instrumentation amplifier with high gain, high CMRR and larger bandwidth is implemented. The proposed differential amplifier may be used for various control systems as well as small signal conditioning circuits; instrumentation amplifier having larger product of gain and bandwidth would encounter maximum application in these desires.
