Abstract:
A clock divider circuit. The clock divider receives m input clock signals each of the same frequency. Each input clock signal after the first has a phase offset of 2π/m from the previous input clock signal. The clock divider divides the frequency of the input clock signals by an integer of division K. The clock divider includes a counter that receives the first input clock signal and provides one or more count signals. The clock divider also includes m flip-flops, of which a first flip-flop receives the first input clock signal at its clock input and provides a first clock output signal. Each flip-flop after the first receives an input clock signal at its clock input and provides a clock output signal, each clock output signal after the first having a 2πK/m phase offset from the previous clock output signal.
