Abstract
A new CMOS wide linear range fully-differential transconductor is proposed. The transconductor employs 5 unbalanced differential pairs with transistor aspect ratios chosen optimally using Padé-type approximation theory. It achieves a linear range of 86mV for a voltage supply of 1V. The total harmonic distortion does not exceed 2% for peak to peak voltages as high as 0.2V and frequencies as high as 1MHz. Monte Carlo simulations revealed that the linear range of the suggested transconductor is not prone to parameter variations.
