This paper presents a new divide-by-2 quadrature injection-locked frequency divider (QILFD). The QILFD consists of a new transformer-coupled quadrature voltage controlled oscillator (QVCO) with the voltage-current feedback technique and two NMOS switches, which are in parallel with the QVCO resonators for signal injection. The proposed CMOS QILFD has been implemented with the TSMC 0.35 mu m CMOS technology and the core power consumption is 16.52 mW at the supply voltage of 2.2 V. The free-running frequency of the QILFD is tunable from 2.85 GHz to 3.07 GHz. At the input power of 0 dBm, the divide-by-2 operation range is from 5.48 GHz to 6.48 GHz. The phase deviation of free running quadrature output is about 0.53 degrees.
