Voltage Level Adapter Design for High Voltage Swing Applications in CMOS Differential Amplifier
This work focuses on circuit level technique that achieves high swing in single ended output differential amplifiers like differential amplifier with active current mirror load, telescopic cascode, folded cascode etc. This technique is designed in such a manner that it can be visualized as a 2-terminal black box. Now, these 2-terminals can be connected to the conventional single ended differential amplifiers enhancing their swing without degrading other parameters like gain, bandwidth, CMRR etc. This black box achieves its performance consuming less power and minimum circuitry area. All the simulation characterization and validation has been made through UMC 180 nm technology node in Cadence.
