Abstract

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 V~dd~ 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 V~dd~ = 1.2 V. © 2009 Wiley Periodicals, Inc.
