چکیده
In this paper is presented a novel constant transconductance CMOS differential amplifier. The circuit uses a modified CMOS inverter to process polarisation currents of the complementary differential amplifier in order to maintain constant transconductance over the entire common-mode input voltage range. Simulation shows error less than ±6.12 % for a single supply voltage of 1.5 V. Key-Words: low voltage, rail-to-rail differential amplifier, constant transconductance differential amplifier

This paper proposes a low voltage (±0.55V supply voltage) low power (44.65µW) high common mode rejection ratio (CMRR) differential amplifier (d.a.) with rail to rail input common mode range (ICMR), constant transconductance (gm) and enhanced frequency performance. Its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...

Presented is a 0.9 V rail-to-rail constant gm CMOS amplifier input stage consisting of complementary differential pairs and a gm control circuit. The gm control circuit eliminates the gm dead zone, which occurs in the conventional rail-to-rail amplifier with ultra-low supply voltages. The proposed amplifier input stage has a constant gm that varies by +2.3% for rail-to-rail input common-mode le...

A 1 V rail-to-rail constant-gm CMOS operational amplifier is proposed. This study shows that keeping the sum of currents in the complementary differential pairs constant rather than controlling the tail currents produces a constant-gm input stage operating in the weak inversion. The currents in the n-channel differential pair are regulated to keep the sum of currents in the complementary differ...
