An Enhancement of Recycling Folded Cascode Amplifier Using Potential Divider Method

This paper is about how a Recycling folded cascode amplifier is designed and challenges faced while designing it,the recycling folded cascode amplifier demonstrates better performance in terms of gain, unity gain frequency, and slew rate. Designers typically have difficulty keeping all of the transistors saturable to achieve the intended performance of gain-boosting amplifier circuits utilising cascode topologies. Analog circuit designers can use the potential distribution approach to ensure that all of their transistors are operating in saturation. We are designing our recycling cascode amplifier using potential distribution method. A gain of 64.96 dB with a unity gain frequency of 67.40 MHz at a bandwidth of 39.7 kHz, when driving a load capacitance of 1pF is obtained. Also provides a phase margin of 73.4 at a power dissipation of 180 μW. We are simulating it in cadence virtuoso with 180 nm technology.
