Description
Summary:	A novel divide by five injection-locked frequency divider (ILFD) is suggested and was manufacture in the 0.18 μm 1P6M CMOS from tsmc. Normal harmonic mixer divide-by-5 ILFD has finite locking range. This design proposed a wide locking range divide-by-5 ILFD, which is lean against voltage-controlled oscillator (VCO) by a capacitive cross-coupled. Resistors are included in the resonator to prolong the locking range. At the drain-source bias V DD of 0.9V and at the accessary power of 0dBm, the locking range is 3.3GHz of the divide-by-5 ILFD, from the accessary frequency 9.2 GHz to 12.5 GHz, the calculated is 30.6%. The core consumption is 2.7mW. The chipset dimension is 0.987 × 1.096mm 2 .
