Abstract :
This paper introduces a high speed, low power CMOS 15/16 dual-modulus prescaler (DMP) based on true single-phase-clock (TSPC) and transmission gates (TGs) cell. A glitch elimination TSPC is used in the synchronous counter. TGs are used in the critical path. The DMP circuit implemented in 0.18μm CMOS process. The simulation results are provided. It shows wide operating frequency from 0.5GHz to 3.125GHz. It consumes 4.23mW with 1.8V power supply voltage at 3.125GHz.
