Abstract :
A new high-speed divide-by-4/5 counter is developed. Based on this divide-by-4/5 counter, a 3 V 2 M ~1.1 GHz dual-modulus divide-by-128/129 prescaler fabricated with 0.6 μm CMOS technology is presented. Its maximum operating frequency of 1.11 GHz with power consumption of 19.2 mW has been measured at a 3 V supply voltage. In addition, for a power supply of 1.5 V, the circuit consumed 2.67 mW at a maximum input frequency of 520 MHz
