A New High-Gain Operational Amplifier Using Transconductance-Enhancement Topology Integrated With Metal Oxide TFTs

This paper presents an integrated operational amplifier (OPAMP) consisting of only n-type metal oxide thin-film transistors. In addition to using positive feedback in the input differential pair, a transconductance-enhancement topology is applied to improve the gain of the OPAMP. The OPAMP has a vol...
