ABSTRACT:
A MOS differential voltage-to-current converter circuit has first and second MOS transistors forming a differential pair and a resistor connected between the sources of the first and second MOS transistors. These first and second MOS transistors are connected to the sources of third and fourth MOS transistors, at respective sources. By biasing the third and fourth MOS transistors, with a constant current, differential input voltage is supplied to the gates of the third and fourth MOS transistors. The drain outputs of the third and fourth MOS transistors are respectively connected to first and second signal transmission circuits for transmitting the drain outputs to the gates of the first and second MOS transistors through the first and second signal transmission circuits. With taking the current flowing through the first and second MOS transistors as a differential output, a voltage-to-current conversion characteristics not depending upon variable property of the MOS transistors can be obtained.
