Abstract
- The paper presents a comprehensive analysis of signal intermixing taking place across the injectors of frequency-divide-by-three circuits with divide-by-two secondary locking. The analytical results confirmed by circuit simulations provide an insightful understanding of the circuit operation, and inspire the design of a novel single-inductor injection-locked frequency divider (ILFD) by three, where injection is reinforced by a dual-injection scheme with no penalty in power dissipation. The novel circuit, when benchmarked against existing ILFD topologies, optimized in a 65-nm LP CMOS process, shows about a three-time larger locking range with respect to the single-inductor divider by three with a floating-source injector, and about a 40% improvement with respect to the single-inductor divider by three with divide-by-two locking, for the same power dissipation. The novel topology has been adopted in a 15-GHz divider by three for a 5G radio-frequency synthesizer, reaching a 23.6% locking range at 1.56-mW dc power, featuring one of the best performances among divide-by-three ILFDs and a compact size of only 0.09 mm2.
