<p>A differential output stage (260) is provided configured for receiving differential input signal comprising a first signal and a second signal, comprising a first output (233) for providing a first output signal, and a second output (243) providing a second output signal, the first and second output signals together forming a differential output signal, a first voltage buffer (232) and a first controlled current source (234) each connected to the first output, the first voltage buffer being driven by a signal in-phase with the first input signal, the first controlled current source being driven by a signal in-phase with the second input signal, and a second voltage buffer (242) and a second controlled current source (244) each connected to the second output, the second voltage buffer being driven by a signal in-phase with the second input signal, the second controlled current source being driven a signal in-phase with by the first input signal.</p> |
