title = "A Gm-C operational amplifier for analog signal processing",
abstract = "A low-voltage rail-to-rail constant transconductance (gm) operational amplifier with simple shunt feedback bias is presented in this paper. Complementary differential input pairs are employed to realize rail-to-rail input. By using the shunt feedback bias, the influence of channel length modulation effect can be cancelled off to keep gm constant. Simulation results under SMIC 40nm CMOS process and 1.1V supply voltage are provided in this study, which demonstrates ±1\% of gm variation in [0.02V, 0.3V] and [0.7V, 1V] input voltage region. By using a gm control circuit and a voltage shift structure, the gm variation in the entire input range performs within ±1.6\% for low gm and ±2.3\% for high gm. And the consumed area is only 4\% of the conventional topology.",
