Abstract:
A phase rotator includes a phase selector stage operative to receive a clock signal and output a first phase and a second phase of the clock signal, a slew rate control stage including a first pass gate circuit operative to control a slew rate of the first phase of the clock signal and a second pass gate circuit operative to control a slew rate of the second phase of the clock signal, and a phase blending stage operative to combine the first phase with the second phase of the clock signal and output a phase rotated signal.
