A 26-44 GHz Programmable Frequency Divider for Wideband MM-Wave

The design of a 44 GHz programmable divider with a division range of256-508 for millimeter wave application, is presented, using a 55 nm CMOS technology. The divider consists of a divide-by-4 input stage, a prescaler that implements mixture structure D flip-flops to enhance operating speed, two subtraction counters and control logic. By using a new control logic circuit structure with transmission gate optimized the speed and power dissipation of the whole divider. The simulation results show a wide frequency range of 26-44 GHz, a power consumption of15.2 mW under 1.2 V power supply.
