A Low Power 185 GHz Static CML Frequency Divider in SiGe HBTs Using Band-switching Technique in 45nm PDSOI BiCMOS

This paper presents a current-mode logic (CML) frequency divider in a 45nm PDSOI BiCMOS technology. The divider achieves high-frequency and low-power operation. Inductive peaking with PMOS switches is used for band selection and bandwidth extension. The divider achieves a maximum dividing frequency of 185 GHz and a bandwidth of 170 GHz with input power less than 0 dBm. The circuit consumes only 12 mW in a 1.6 V supply and occupies only 400 x 600 um
