| dc.description.abstract | This thesis is composed of three parts. The first part presents the design and measurement results of a millimeter-wave injection-locked frequency divider (ILFD) intended for 28GHz phased-array transceiver systems, implemented using a 90-nm CMOS process. The second part describes the design and measurement of a Q-band image-rejection mixer for astronomical receivers, fabricated using the 90-nm CMOS technology. The third part focuses on the design and measurement results of a Q-band variable-gain power amplifier (VGPA) targeted for astronomical receiver applications, likewise implemented in a 90-nm CMOS process.
In the first part, an injection-locked frequency divider is proposed for a 28 GHz phased-array system. The circuit adopts a Class-C biasing technique to reduce power consumption significantly and employs a dual-mixing technique to extend the locking range without additional power consumption. Furthermore, harmonic suppression capacitors are utilized to minimize the core chip area. Measurement results show a locking range from 21 to 36 GHz, with a low power consumption of 0.7 mW and a compact core area of only 0.043 mm². The second part presents a Q-band image-rejection mixer designed for astronomical receivers. The mixer utilizes a cold-biasing technique to achieve a wide IF bandwidth and adopts a double-balanced architecture to enhance isolation. A Wilkinson power divider and a coupler are incorporated to suppress the image signal effectively. Measurement results demonstrate an IF bandwidth ranging from 4 to 40 GHz, with a conversion loss between –11.5 dB and –14 dB, and an image rejection ratio exceeding 30 dB across the operational bandwidth. Notably, this design operates with zero DC power consumption. The third part proposes a Q-band variable-gain power amplifier for astronomical receivers. A sandwiched transformer is employed at the output stage to reduce insertion loss, and a new gain-control architecture is introduced to maintain stable input and output impedances across different gain settings, thereby improving circuit stability. Measurement results indicate a 3-dB bandwidth from 36.8 GHz to 52.6 GHz, a gain control range of 5.5 dB, and a saturated output power (Psat) of 17.2 dBm. It is worth mentioning that the OP1dB exhibits minimal variation under different gain conditions. | en |
