Abstract
A system and method for performing voltage to current conversion, the system comprising of a first set of devices that senses the input voltage signal through its input terminal and replicates said input voltage across a second set of devices which then converts said replicated input voltage signal to an output current signal; a third set of devices that transfers the output current signal to output terminals; a differential feedback loop comprising an amplifier positioned between a first one of the first set of devices and a first one of the third set of devices; and a common mode feedback loop that regulates the output average voltage to a reference voltage.
