ABSTRACT:
A voltage-to-current converter comprises a first MOS transistor for receiving a voltage signal at a first gate and transferring a current signal between a first drain and a first source, a second MOS transistor for receiving a biasing voltage at a second gate and transferring the current signal between a second drain and a second source, and a biasing circuit for applying the biasing voltage of V.sub.C +V.sub.T +kV.sub.DS to the second gate such that the second transistor provides a substantially constant drain-to-source resistance of 1/.beta.V.sub.C, where V.sub.C is a constant voltage, V.sub.T is a threshold voltage for the second transistor, V.sub.DS is a drain-to-source voltage for the second transistor, k is a constant in the range of 1/3 to 2/3, and .beta. is a gain for the second transistor.
