摘要:
In one embodiment of the invention, a method for convolution of signals is disclosed including generating four phased half duty cycle clocks each being out of phase by a multiple of ninety degrees from the others; coupling the four phased half duty cycle clocks into a four phase half duty cycle mixer; and switching switches in the four phase half duty cycle mixer in response to the four phased half duty cycle clocks to convolve a differential input signal with the four phased half duty cycle clocks to concurrently generate a differential in-phase output signal and a differential quadrature-phase output signal on a dual differential output port.
