Kaliyath, Y.Laxminidhi, T.2026-02-0620162016 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics, DISCOVER 2016 - Proceedings, 2016, Vol., , p. 237-241https://doi.org/10.1109/DISCOVER.2016.7806229https://idr.nitk.ac.in/handle/123456789/32205This paper presents a low power 1.8 V single-ended operational trans conductance amplifier (OTA) with a very high dc gain targeted for audio applications. Cascoding and gain boosting are employed to achieve the high gain. The amplifier is implemented in UMC 180 nm CMOS technology. For a typical process corner, the amplifier provides a dc gain of 113.62 dB and a unity gain bandwidth of 2.49 MHz at 62.9° phase margin with capacitive load of 2.5 pF. The amplifier consumes only 6.12 μA of quiescent current from 1.8 V supply. The amplifier exhibits good performance across all the process corners with the use of body bias technique. © 2016 IEEE.
