This paper presents design and implementation of a two stage operational amplifier with gain boosted, source follower buffer. The circuit operates efficiently in a closed loop feedback system to solve many impedance issues and makes it suitable for high speed applications. Any fluctuations in supply voltage or dc input voltages can be nullified and stabilizes the operation of the circuit producing large output gain. This architecture also neutralize the effects such as ringing and overshooting in frequency response. 0.6um technology using cadence is used to implement the amplifier. The Op-amp designed here exhibits a noticeable10^4.35 DC differential gain.
