Abstract
A circuit includes a first pair of transistors connected in parallel between a first node and a second node with a diode-connected transistor coupled to the second node. A second pair of transistors has current terminals connected at a third node. A first and second current sink transistors are connected in a current mirror configuration with the diode-connected transistor and further coupled to the third node. A first differential amplifier has an output coupled to control terminals of the first and third transistors and an input coupled to a further current node of the third transistor. A second differential amplifier has an output coupled to control terminals of the second and fourth transistors and an input coupled to a further current node of the fourth transistor.
