Abstract:
The present invention relates to 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.

Claim (Index 1):
Differential voltage-to-current conversion circuitry, comprising:\n a power supply node for connection to a power supply voltage source; a first current path extending from the power supply node via a first intermediate node to a first load node to provide a first load current at the first load node for use by load circuitry when connected to the first load node, wherein a first supply-connection impedance is connected along the first current path between the poser supply node and the first intermediate node and a first load-connection impedance is connected along the first current path between the first intermediate node and the first load node; a second current path extending, in parallel with the first current path, from power supply node via a second intermediate node to a second load node to provide a second load current at the second load node for use by the load circuitry when connected to the second load node, wherein a second supply-connection impedance connected along the second current path between the power supply node and the second intermediate node and a second load-connection impedance is connected along the second current path between the second intermediate node and the second load node; a differential voltage input connected between the first and second intermediate nodes via first and second input-connection impedances, respectively, for application of a differential input voltage signal, supplied at the differential voltage input, between the first and second input-connection impedances so that the first and second load currents together define a differential current signal dependent on the differential input voltage signal; and control circuitry, wherein: the first and second load-connection impedances are implemented as first and second transistors, respectively; and the control circuitry configured to control a bias voltage provided to the gate or base terminals of the first and second transistors so as to control a gain relationship between the differential input voltage signal and the differential current signal.
