Summary :

A dual-band divide-by-2 quadrature injection-locked frequency divider (QILFD) is proposed to achieve high-speed, low power, wide-locking range, and accurate quadrature output phases. The QILFD consists of two dual-resonance differential voltage controlled oscillators and four coupling NMOS injectors in a ring configuration. The injectors are used as coupling devices of two differential ILFDs and are also used as common source amplifiers. The proposed QILFD has been implemented with the TSMC 90 nm CMOS technology and the core power consumption is 2.31 mW at the dc drain-source bias of 0.5 V. At the input power of 0 dBm, the low-band and high-band divide-by-2 operation ranges are respectively from 7.0 GHz to 10.1 GHz and 19.8 GHz to 24.6 GHz.
