Abstract
A transistor resistor and an associated method are provided to improve the resistance linearity of the transistor resistor. The transistor resistor includes a transistor operating in the resistive region, where the drain and source of the transistor receive an input signal and an output signal respectively. The transistor resistor also includes a compensating circuit for generating a compensating signal according to the input signal. The compensating signal is provided to the gate of the transistor such that the voltage difference between the gate and source of the transistor approximates to a constant.
