Abstract
A frequency divider in accordance with the present invention includes a plurality of latch circuits connected together in series to which a clock signal and an inversion clock signal are input, an inverter circuit to which an output signal from a last connected one of the latch circuits is input, an output terminal to which an output from the inverter circuit is connected, and a plurality of feedback paths that connect the output from the inverter circuit to respective inputs of the plurality of latch circuits. The frequency divider further includes a switching circuit that switches connections to the plurality of feedback paths so that an output signal from the inverter circuit is input to only one of the plurality of latch circuits.
