Abstract | A new divide-by-3 injection-locked frequency divider (ILFD) is proposed. The ILFD consists of a 7.6GHz voltage controlled oscillator (VCO) and two transformers, which are in series with the cross-coupled transistors in the VCO for signal injection. The proposed CMOS ILFD has been implemented with the TSMC 0.13m CMOS technology. At the supply voltage of 0.8 V, the core power consumption is 1.25mW, and the free-running frequency of the ILFD is tunable from 7.2 to 7.87GHz. At the input power of 0dBm, the total divide-by-3 locking range is from 21.56 to 23.63GHz as the tuning voltage is varied from 0.0 to 0.8 V. The phase noise of the locked ILFD output is lower than that of the free-running ILFD in the divide-by-3 mode. © 2009 The Institution of Engineering and Technology. |
