Abstract
This letter designs a wide locking range high modulus ILFD designed in a foundry 0.18 μm CMOS process. The proposed LC ILFD uses two stacked LC ILFDs sharing the same dc current. The top ILFD is used as a ÷2 ILFD and the bottom ILFD is used as a ÷4 ILFD; the latter ILFD is used as the input device and the former ILFD is used as the output device. The ÷4 ILFD uses a multi-resonance resonator as shown experimentally by non-overlapped locking ranges. At the incident power of 0 dBm, the locking range is 4 GHz (38.835 %), from the incident frequency 8.3 GHz to 12.3 GHz. The ILFD core power consumption is 13.98 mW and the die size is 1.2 × 1.2 mm2.
