题目:An Adaptive Biasing One-Stage CMOS Operational Amplifier for Driving High Capacitive Loads
作者:Harald Parzhuber,Wolfgang Steinhagen
摘要:An adaptive biasing one-stage CMOS operational amplifier for driving high capacitive loads has been developed. The amplifier has been designed to drive LCD’s in battery-supplied devices. Contradictory features like low power dissipation and high driving capability at low supply voltage are required. Complementary differential input stages provide rail-to-rail common-mode input range. With a special cross-coupled double-to-single-ended conversion, a full supply output range is achieved. These improvements solve a functional problem of some existing adaptive biasing amplifiers.
