摘要
We present a dual-modulus prescaler manufactured in SiGe bipolar technology. The circuit has selectable divide ratios of 256 and 257 and is intended for use in frequency synthesizers. It operates up to a maximum frequency of 20 GHz with a supply voltage of 2.3 V and a power consumption of only 27 mW.
