Document Type and Number:
Japanese Patent JP5328903
Kind Code:
B2
Abstract:
The present invention provides a CMOS-inverter-type frequency divider circuit that can further reduce power consumption. The CMOS-inverter-type frequency divider circuit includes: a plurality of CMOS inverters that contribute to realizing a frequency division function; a frequency division control section for performing control such that some or all of the plurality of CMOS inverters are intermittently driven at the respective different timings in accordance with an input signal; and a drive power supplying section for supplying powers for driving the plurality of CMOS inverters, and for, based on state information indicating whether VCO sub band selection or normal transmission is performed, switching some or all of the powers for the plurality of CMOS inverters between the VCO sub band selection and the normal transmission.
