Time-Domain ADPLL BPSK, QPSK, and 8PSK Demodulators
Journal of Electrical and Computer EngineeringTime-domain all-digital-phase-locked-loop phase-shift-keying (PSK) demodulators are proposed for BPSK, QPSK, and 8PSK signals. The demodulator architectures are highly suitable for low-voltage nanoscale CMOS techology.

IET Circuits, Devices &Systems, Volume 17, Issue 1, Page 13-28, January 2023., 2023 A dual‐path signal‐superposition technique that can address issues which pose challenges in the designs of high speed I/Os with low electro‐magnetic interference/radiations (EMI/EMR) applications is proposed. This work demonstrates an output slew rate lower than 1 V/ns at data rate of hundreds of Mbps or above over PVT, without using huge on‐board ...

IET Communications, Volume 16, Issue 20, Page 2492-2500, December 2022., 2022 Abstract Direct RF sampling has been suggested as a solution for receivers that are flexible in frequency and across standards, while utilising only a single radio frequency front‐end. However there are concerns about their robustness in the presence of out‐of‐band and in‐band blockers.

Electronics Letters, Volume 58, Issue 7, Page 274-276, March 2022., 2022 Abstract The quantisation noise contribution of a conventional FDC phase‐locked loop (PLL) is still high due to the only second‐order noise‐shaping capability. A MASH2‐k FDC PLL architecture enabling (k + 2)th‐order noise shaping for more flexible loop design optimization and for a wider loop bandwidth to suppress the noise from the digitally ...

A 190.3‐dBc/Hz FoM 16‐GHz rotary travelling‐wave oscillator with reliable direction control
Electronics Letters, Volume 57, Issue 5, Page 209-211, March 2021., 2021 Abstract This letter presents a rotary travelling‐wave oscillator (RTWO) with reliable direction control in a standard 130 nm complementary metal–oxide–semiconductor (CMOS) technology. To achieve low phase noise (PN), and low power consumption, 16‐stages customised transmission line segments are designed and simulated on electromagnetic tools.
