Abstract
A phase selector for selecting a differential output is provided. The phase selector can include two matched transistor circuits. A first transistor circuit can receive a first differential input signal whereas a second transistor circuit can receive a second differential input signal. One of the transistor circuits can be used to dump an output current generated by the first differential input signal to Vdd. The other transistor circuit can be used to steer an output current generated by the second differential input signal to two output lines, thereby providing a differential output signal on the output lines.
