Abstract:
1. A frequency generator comprising: a signal generator configured to provide, at a first frequency, (i) a first input signal, (ii) a second input signal, (iii) a third input signal, and (iv) a fourth input signal, wherein the second input signal, the third input signal, and the fourth input signal are respectively phase-shifted from the first input signal by 180, 90, and 270 degrees; a first frequency divider configured to a second frequency divider configured to wherein each frequency divider includes a series of n delay stages that are serially coupled together and that include a first stage and subsequent stages; wherein each stage has two mutually-inverse outputs that provide two of the respective divider's 2n output signals; and wherein each stage imparts a phase delay of 360/n degrees, such that in each respective divider:
