ABSTRACT:
A rail-to-rail voltage-to-current converter converts a variable differential voltage signal having first and second voltage signal components, to an output current signal. The converter includes a first voltage-to-current converter configured to receive a voltage signal component and a reference voltage signal to provide a substantially linear output current signal. A second voltage-to-current converter receives the other one of the voltage signal components and the reference voltage signal to provide a second substantially linear output current signal. An adder combines the first and second output current signals to provide a substantially linear voltage/current characteristic over a wide range of available voltage signals generated by a power supply.
