ABSTRACT:
A frequency multiplier circuit including a circuit element to receive an input signal having a first frequency which is provided to a phase shifting circuit element to provide an intermediate signal resembling the input signal except shifted in phase. This intermediate signal is provided to a logic element which combines the intermediate frequency with the input signal to produce an output signal having a second frequency which is a multiple of the first frequency.
