A 0.18-μm BiCMOS wide locking-range divide-by-2 injection-locked frequency divider with dual-injection Conference Paper

abstract

• A new divide-by-2 injection locked frequency divider (ILFD) with dual-injection technique is proposed. The proposed ILFD is developed with divide-by-2 current mode logic (CML) divider, which is connected at the output of the ILFD to achieve constant output amplitude. Fabricated in 0.18-m BiCMOS process, the proposed divide-by-2 ILFD with dual-injection improves the locking range through simultaneous optimization of loaded quality factor (Q L) and oscillation current amplitude (iosc) while consuming low power. The measured locking range of the proposed ILFD with dual-injection is 692 MHz between 7.512 GHz and 8.204 GHz, which is almost 10 times wider than that of a single-injection counterpart. The core of the ILFD with dual-injection only consumes 2.9 mA with 1.5-V supply. 2014 IEEE.
