Abstract :
A SiGe bipolar dual-modulus ÷64/65, ÷32/33 prescaler implemented in commercially available Infineon SiGe bipolar technology is presented. A maximum operational frequency of 5.5 GHz has been measured for a supply current of 6 mA at 3.3 V. For a reduced supply current of 3.5 mA a maximum frequency of 4.0 GHz has been obtained. A comparison with a purely-Si prescaler clearly demonstrates the enhanced speed-power product of the SiGe technology
