Frequency compensated triple cascode telescopic operational amplifier
In this paper, an RC Miller compensation, a frequency-compensation technique of two-stage Triple Cascode Telescopic Operational Amplifier (Op-Amp) is proposed. It is based on the Miller effect for splitting of poles and pole-zero cancellation. The proposed novel Op-Amp consists of an additional triple Cascode stage at the output. The stacking of Metal Oxide Semiconductor Field Effect Transistors (MOSFET) leads to increased output impedance, resulting in higher gain of the Op-Amp. The designed Op-Amp circuit achieves a high gain of 104.6 dB and a phase margin (PM) of 75.3° for a 1.8 V supply voltage using GPDK 90 nm technology. The gain and PM of the designed Op-Amp have been improved by 98.1% and 47.6% respectively, as compared to conventional Op-Amp circuits.
