A low-power SiGe BiCMOS series-tuned divide-by-3 injection locked oscillators.

An LC-tank oscillator-based divide-by-3 injection locked frequency divider (ILFD) is proposed and the series-tuned Armstrong ILFD were implemented in the 0.35 μm SiGe 3P3M BiCMOS technology. Measurement results show that when the supply voltage Vdd is biased at 1.2 V, the free-running oscillation frequency of the ILFD is tunable from 1.19 GHz to 1.0 GHz, and at the incident power of 0 dBm, the operation locking range is about 0.65 GHz, from the incident frequency 3.03–3.68 GHz. The core power consumption is 2.05 mW at Vdd = 1.2 V. © 2009 Wiley Periodicals, Inc.
