Claim:
1. A quadrature signal generator, comprising: a control block to generate a reference signal and a filter control signal, the filter control signal having a number N of individual control signals based, at least in part, on an input clock signal, wherein the number N is greater than one, wherein each of the N individual control signals has a pulse width approximately equal to a pulse width of the input clock signal and has a duty cycle of approximately 1/N times 100 (1/N*100) percent; a mixer, coupled to the control block, to generate a mixer output signal based, at least in part, on the input clock signal and the reference signal; and an N-path filter, coupled to the mixer and the control block, to filter the mixer output signal and to generate a filter output signal based, at least in part, on the filter control signal, the N-path filter comprising:
