Abstract :
A dynamic divide-by-2 circuit is presented. The frequency divider operates from 74 GHz up to at least 136 GHz, limited by the available input power. A balun is included on chip to convert the single-ended input signal to differential, while maintaining input sensitivity better than 0 dBm over the entire frequency range. The divider core has a low power consumption of 72.6 mW from -3.3 V and is implemented in a 210-GHz-f T SiGe bipolar technology.
