A 300 GHz divide-by-2 ILFD is fabricated in 40 nm CMOS technology. This ILFD adopts pi-type LC networks with a negative coupling technique to enhance the oscillation frequency. The oscillation frequency and the locking range of the proposed ILFD are analyzed. The measured locking range is 297.08-306.64 GHz. The ILFD consumes 9.18 mW under a standard supply of 0.9 V excluding output buffers.
