Abstract
Among the embodiments of the present invention is an apparatus that includes a transistor (), a servo device (), and a current source (). The servo device () is operable to provide a common base mode of operation of the transistor () by maintaining an approximately constant voltage level at the transistor base (). The current source () is operable to provide a bias current to the transistor (). A first device () provides an input signal to an electrical node () positioned between the emitter () of the transistor () and the current source (). A second device () receives an output signal from the collector () of the transistor ().
