Abstract—An analysis of regenerative dividers predicts the required phase shift or selectivity for proper operation. A divider topology is introduced that employs resonance techniques by means of on-chip spiral inductors to tune out the device capaci-tances. Configured as two cascaded 2 stages, the circuit achieves a frequency range of 2.3 GHz at 40 GHz while consuming 31 mW from a 2.5-V supply.
