A wide-locking range SiGe BiCMOS divide-by-3 injection locked oscillators

An active inductor oscillator-based divide-by-3 injection locked frequency divider (ILFD) is proposed, and was implemented in the 0.35 μm SiGe 3P3M BiCMOS technology. Measurement results show that when the supply voltage V
_dd
is biased at 3.0 V, the free-running oscillation frequency of the ILFD is tunable from 3.84 GHz to 3.13 GHz, and at the incident power of 0 dBm and the V
_tune
= 2.5 V, the locking range is about 1.67 GHz, from the incident frequency 10.24 GHz to 11.91 GHz. The core power consumption is 4.32 mW at V
_dd
= 3.0 V.
