Abstract :
A technique for converting a MOSFET into a highly linear, electronically tunable resistor is described. The key to the linearisation achieved is the application of voltages across the gate and across the body, in such a way that the gate-channel and body-channel potentials remain constant all along the channel. Measurements show distortion levels of less than -75 dB for signal amplitudes of 6 V peak to peak.
