  • Voltage-to-current conversion
    Patent number: 10554212
    Abstract: Circuitry for voltage-to-current conversion, and in particular to differential voltage-to-current conversion circuitry. Such circuitry is operable to receive a differential voltage input signal and output a corresponding differential current signal. First and second controllable current sinks are connected to first and second load nodes of the circuitry so as to draw corresponding sink currents from those nodes.
