发明名称	Driver circuit with output common mode voltage control
摘要	A driver circuit having a minimized and/or controllable output common mode voltage comprises a differential amplifier having, a passive element as a biasing source for establishing a bias current in the differential amplifier and a control amplifier operatively coupled to the differential amplifier in a feedback arrangement, the control amplifier generating a control signal. The differential amplifier is responsive to the control signal for providing a voltage at an output of the driver circuit that is substantially independent of an input signal presented to an input of the driver circuit. By eliminating the need for an active device (e.g., transistor) as a bias current source, the output common mode voltage of the driver circuit is minimized. A reference signal coupled to the control amplifier, in conjunction with the feedback arrangement, substantially fixes the output common mode voltage of the driver circuit to a predetermined value.
