Abstract

A modified nested-current-mirror (NCM) Single-Stage amplifier, for high-performance, liquid crystal display panels, is presented in this paper. The proposed NCM is more than 8 times faster than the original NCM structure, without any extra static power consumption. Slew rate of the NCM is improved 10 times and DC-gain is also improved 6 dB, while the power consumption, gain-bandwidth product, output voltage swing range, and the phase margin of the NCM are not affected to great extent and the input-referred-noise is reduced 12%. Proposed NCMs achieve relatively higher figure of merit in comparison to previously reported NCM amplifiers and other state-of-the-art works. The significant performance improvement is obtained due to a novel slew-rate enhancer circuit. The simulation results for the designed NCM in a typical 90 nm CMOS technology confirm the predicted performance improvements.
