A D-band divide-by-6 injection-locked frequency divider with Lange-coupler feedback architecture in 0.13 µm SiGe HBT

A D-band divide-by-6 injection-locked frequency divider (ILFD) is presented. The basic mechanism of high division ratios frequency divider is investigated. The circuit employs a wideband microstrip Lange coupler, a microstrip delay line and a pair of Cascode transistors to form a feedback loop for enhanced divide-by-6 operation. The proposed ILFD is fabricated with chip size of 0.7 × 0.9mm2 in ...

Design of Injection-Locked Frequency Divider in 65 nm CMOS Technology for mm-W applications

In this paper, an Injection Locking Frequency Divider (ILFD) in 65 nm RF CMOS Technology for applications in millimeter-wave (mm-W) band is presented. The proposed circuit achieves 12.69% of locking range without any tuning mechanism and it can cover the entire mm-W band in presence of Process, Voltage and Temperature (PVT) variations by changing the Injection Locking Oscillator (ILO) voltage c...

A 3.3 µW dual-modulus frequency divider with 189% locking range for MICS band applications

This paper presents the design and simulated performance of an ultra-low-power 4/5 frequency divider based on a CMOS ring oscillator. The divider operates over a 189% locking range (29MHz – 1GHz) for both division ratios, covering the MICS band and 433MHz and 915MHz ISM bands while consuming only 3.3 μW in MICS band. The wide locking range and low power consumption makes this very suitable for ...
