Abstract:

Frequency synthesizer is one of the important elements for wireless communication application. The speed of VCO and prescaler determines how fast the frequency synthesizer is. A dual modulus prescaler contains logic gates and flip-flops. To fulfill the need of high frequency and low voltage circuit suitable flip-flops must be selected. The prescaler is a circuit employed in high frequency synthesizer designs. In the proposed circuit the technique called the True Single Phase Clock (TSPC) technique, was applied.Divide-by-2/3 prescaler is implemented by TSPC flip-flops. Divide by 32/33 prescaler is implemented by choosing various combinations of 2/3 prescaler and flip-flops. The DMP circuit implemented in 45nm CMOS process and simulation was carried out in Tanner EDA tool. The simulation results are provided. It consumes 86.42µWwith 1V power supply voltage at 2.4GHz.
