A 321 static frequency divider consisting of five stages of 21 dividers using current mode logic CML was fabricated in a 130-nm bulk complementary metal-oxide semiconductor CMOS logic process. By optimizing transistors size, high operating speed is achieved with limited power consumption. For an input power of 0 dBm, the 321 divider operates up to 26 GHz with a 1.5-V supply voltage. The whole 321 chain including buffers consumes 8.97 mW and the first stage consumes only 3.88 mW at a 26-GHz operation. The power consumption of the first 21 stage is less than 15 of other bulk CMOS static frequency dividers operating at the same frequency.
