A linearized technique in an All-MOS transconductance amplifier
A linearized technique in an all-MOS transconductance amplifier is presented. This proposed technique utilizes a simple source follower without the need of complex circuits. The linearization principle and the design methodology are demonstrated in this paper. The corresponding circuit has been fabricated in a 0.35 ? m CMOS technology, and its active chip area is 145.8  79.6 ? m 2 . From the experimental results, the proposed technique improves the nonlinearity error from 10.92% to 0.64% at a 3.3V supply voltage.
