摘要：

Dual-modulus prescalers based on programmable Injection-Locked Frequency Dividers (ILFDs) are presented. With a multi-phase injection, variable division ratios are obtained by simply switching different number of input signals. Implemented in a 0.18 mu m CMOS process, the 4/5 dual-modulus prescaler achieves an operating range of 1.8-6GHz with 0.22mW measured power consumption from a 1V supply. Based on the same architecture, a 0.15mW 5GHz 2/3 dual-modulus prescaler and a 0.29mW 5.5GHz 8/9 dual-modulus prescaler are also demonstrated.
