Title:
Frequency dividing phase shift circuit
Abstract:
A frequency dividing phase shift circuit includes a first frequency divider and a second frequency divider. The first frequency divider is configured to perform 1/(2n+1) (n is a natural number) frequency division on an input signal having a frequency of (freq*2(2n+1)) ("freq" indicates a frequency) to generate a first signal having a frequency of (freq*2). The second frequency divider is configured to perform 1/2 frequency division on the first signal to generate 4-phase signals which are different in phase by 90 degrees one after another.
