Abstract
This paper presents a comparison on Complementary and Recycling FC Amplifier. Complementary folded cascode amplifier is having large O/P swing with high gain of ordinary amplifier in complementary form. This is important to re-circuit again and again for their better slew rate, gain, bandwidth and transconductance. Recycling FC amplifier is similar to complementary FC amplifier and power can be recycled with few input parameters, to make simpler and easy to analyse. The cascode amplifier is connected with common source terminal and common gate terminal. The bandwidth of cascode amplifier is high because of the miller effect, it is eliminated. The system is connected with cascode and overall gain is high, takes few transistors for design of a cascode amplifier. A SR can allow frequency up to the range for that will eliminates unwanted signal. A unity gain bandwidth is applied to eliminate smaller signal. A SR of complementary FC amplifier is good at 3.3V/µs where as 6.3V/µs is for recycling folded cascode amplifier. The power consumption is 690µW and 710µW of complementary folded cascode and recycling folded cascode amplifier respectively. The voltage gain is above 70.7% of is considered as amplification for all ranges of its amplitude.
