Abstract
An ultra-high current efficiency current recycling folded cascode amplifier is presented in this paper. To improve the current efficiency of conventional recycling folded cascode amplifier, it utilizes adaptive biasing class-AB input stage and local common-mode feedback techniques, leading to a boost in gain-bandwidth and slew rate. Both conventional and proposed recycling folded cascode amplifiers are designed on CSMC 180â¯nm process. Simulation results demonstrate that the proposed current recycling amplifier achieves 3.2 times the gain-bandwidth and 7.7 times the slew rate that of traditional counterpart with only 25% additional power consumption.
