摘要: A high speed dual modulus prescaler aims to be used on a frequency synthesizer of wireless communication systems to divide frequency of input signals. The high speed dual modulus prescaler includes a first D flip-flop, a second D flip-flop and a main control transistor. The main control transistor switches connection of the first D flip-flop and second D flip-flop. The main control transistor provides an OR gate state and an AND gate state to form an OR gate circuit and an AND gate circuit in the prescaler. Thereby the number of transistors in the prescaler can be reduced to increase operation speed and lower power consumption.

The pulse generator includes a first N-transistor, a second N-transistor, a third N-transistor, a first inverter and a first P-transistor located on the first conductive line. The first N-transistor is connected to the first connection point and first conductive line. The second N-transistor and the third N-transistor are connected to the first conductive line, a second conductive line and a third conductive line. The first inverter is connected to the second conductive line. The present invention aims to reduce leakage power in a high level fabrication process, and can save power consumption and power-delay-product more than 17% over the conventional pulse triggered flip-flop, and also provides a smaller size of total transistors to lower average leakage current power consumption by 2.4 times.
