Abstract
An apparatus includes an integrated circuit (IC). The IC includes a current source, to sink or source an output current, in response to a control signal, and a switch-capacitor resistor coupled to the current source. The apparatus further includes a controller coupled to derive the control signal from a voltage across the switch-capacitor resistor, the controller further to provide a switch control signal to the switch-capacitor resistor.
