Abstract :
The design and analysis of a D-band divide-by-6 injection-locked frequency divider (ILFD) are presented. The circuit employs a microstrip Lange coupler, a microstrip delay line, and a pair of Cascode transistors to form a feedback loop with a center natural frequency of 24GHz to achieve a divide-by-6 frequency division operation. The proposed ILFD is fabricated in a 0.13μm SiGe HBT technology and occupies a silicon arngea of 0.7×0.9mm2. The developed chip shows frequency-division locking range from 135GHz to 150.2GHz with 2dBm input signal while consuming 5.25mW to 14.4mW including the output buffer amplifier. A phase noise of -121.58dBc/Hz at 1MHz offset is achieved at 150.2GHz.
