Design considerations for a highly linear electronically tunable resistor
Kostis Vavelidis, Y. Tsividis · 1993 IEEE International Symposium on Circuits and Systems · 2002
Design considerations are presented for a linear, electronically tunable resistor. A MOSFET is converted into a highly linear resistor by the application of voltages in such a way that the gate-channel and body-channel potentials remain constant all along the channel, as well as independent of signals.>
