摘要
An integrated circuit complementary metal-oxide silicon (CMOS) voltage controlled oscillator (VCO) includes a plurality of variable delay elements, connected in a ring configuration, each variable delay element including a pair of parallel connected differential CMOS sections. The parallel-connected differential CMOS sections of each variable delay element are controlled by a differential control voltage whose magnitude sets relative levels of operation of the two differential sections of each variable delay element. These relative levels of operation determine the delay through the variable delay element. A current mirror circuit provides the differential control voltage.
