Abstract
A simply fully-differential transconductor is presented that achieves, based on cancellation of first and higher order nonlinearities, +or-0.7% linearity error over a +or-6.4 V differential input range for +or-5 V power supplies. Common-mode input signals are cancelled at the output. The transconductance can be tuned at least by a factor 3 and f(-3dB) is 63 MHz for 10 mu m channel length.
