An unique time-interleaved dual injection locking scheme has been devised to enable ultra high-speed and low-power frequency division with extended frequency locking range. To prove the concept, two frequency dividers (or prescalers) have been realized in 65nm digital CMOS: one divides continuously from 158GHz to 195GHz (or 21% locking range) with input signal ≪ 0dBm and the other divides from 181GHz to 208GHz (or 14% locking range) with input signal ≪ −1dBm. Both prescalers consume ≪ 2.5mW at… CONTINUE READING
