Abstract
The current-voltage regulator has a reference voltage source with an output. Two transconductance amplifiers each have two inputs and a current output. The current outputs of the transconductance amplifiers are coupled to one another and form an output of the current-voltage regulator. One of the inputs of the transconductance amplifiers is coupled to the output of the reference voltage source, and the other inputs of the transconductance amplifiers are driven, respectively, by a current sensor signal and a voltage sensor signal.
