High Gain OPAMP with Positive Feedback by rajul23 is a document available to read on EtoBox.
This paper discusses a fully integrated operational amplifier (OPAMP) with positive feedback using flexible a-IGZO TFT technology, achieving a phase margin of 70°. The OPAMP demonstrates an open-loop gain of 19 dB, a bandwidth of 25 kHz, and a unity-gain frequency of 330 kHz, making it notable for its high phase margin among similar technologies. The design incorporates innovative techniques to compensate for threshold voltage shifts and reduce chip area, resulting in a compact amplifier with effective perf
