摘要
A low-voltage, high-performance voltage differencing buffered amplifier (VDBA) designed using differential flipped voltage followers (DFVF) is presented in this paper. The proposed VDBA is capable of providing high transconductance and wide bandwidth (BW) with low biasing currents and buffer transfer ratio close to unity. Mathematical formulations for transconductance and buffer transfer ratio are deduced through low-frequency small signal analysis. Pre and post layout simulations for characterization of the proposed structure are carried out on Cadence Virtuoso using gpdk 0.18-mu m CMOS process parameters. The transconductance of the proposed VDBA is observed to be varying from 411.8 mu S to 1.374 mS for a corresponding bias current range of 10 to 75 mu A, and the 3-dB bandwidth (BW) is recorded to be 1.2 GHz. The PVT analysis is carried out to show the effect of process corners. To check the robustness of the proposed VDBA, Monte Carlo analysis is performed, and results have been included in the form of histograms.
