Abstract
This letter presents a wide locking range variablemodulus LC ILFD designed with a dual-resonance resonator and the designed circuit was manufactured in the TSMC 0.18 µm CMOS process. The CMOS circuit’s die area is 1.02×0.93mm2. The ILFD can be used as a wide locking range divide-by-2, -3, -4 and -5 circuit, and it is found that the harmonic mixer is used for the divide-by -5 ILFD while other modulus ILFDs use the linear mixer approach. Consequently, wide-locking range is obtained for variable division ratio.
