Abstract :
A static CML divide-by-2 frequency divider is integrated in 65nm SOI CMOS. The maximum operating frequency is 90GHz while dissipating 52.4mW. The self-oscillation frequency is 92GHz with 0.57pJ switching energy. Measurement of self-oscillation frequency at multiple bias conditions enables estimation of the variation in threshold voltage, capacitance, and resistance.
