Abstract :
The paper proposes a voltage-controlled grounded resistor. The principle of the proposed circuit is nonlinearity term cancellation of a MOS operating in the ohmic region. The circuit consists of a nonsaturation-operated MOS transistor and a voltage adder circuit. Its advantage over other grounded resistors is that this circuit uses a single low voltage power supply. Simulation results are carried out by using PSpice.
