Floating bias class ab
WebA highly linear fully self-biased class AB current buffer designed in a standard 0.18 μ m CMOS process with 1.8 V power supply is presented in this paper. It is a simple structure that, with a static power consumption of 48 μ W, features an input resistance as low as 89 Ω , high accuracy in the input–output current ratio and total harmonic distortion (THD) … WebSep 17, 2024 · A low output resistance and high slew rate class-AB flipped voltage follower (FVF) cell is presented in this paper. The proposed FVF cell consists of cascoding transistor which provides the extra gain to the feedback loop and leads to the low output resistance while the bulk-driven transistor acts as an adjustable current source to increase the …
