Special Issue Information

Dear Colleagues,

The rapid progress of complementary metal–oxide–semiconductor (CMOS) technologies has enabled highly integrated, low-power, and scalable sensor platforms. CMOS-based sensors and biosensors are increasingly used in health monitoring, point-of-care diagnostics, environmental monitoring, lab-on-chip systems, the Internet of Things (IoT), and related applications. We are pleased to invite contributions to this Special Issue on Advances in CMOS Integrated Sensors and Biosesnors.

This Special Issue aims to showcase high-quality research and review articles on recent developments, challenges, and applications of CMOS-integrated sensing systems. Contributions should emphasize scientific innovation, technological advancement, and application-driven impact. Both original research articles and reviews are welcome. Relevant topics include, but are not limited to:

  • Cutting-edge system-on-chip solutions for diverse sensing applications;
  • Innovative wearable, implantable, handheld, and ingestible CMOS sensors;
  • Advanced approaches to improving reliability, calibration, energy efficiency, noise performance, and scalability in CMOS sensors and high-throughput arrays;
  • Smart and intelligent CMOS sensing systems;
  • Wireless and IoT-enabled CMOS sensors;
  • Emerging CMOS transducer concepts and modeling techniques;
  • Hybrid integration of CMOS sensors with novel materials;
  • Breakthrough sensing mechanisms and techniques using CMOS integrated circuits.

We look forward to your contributions.

Traditional zero-compensation techniques employed to improve sub-sampling phase-locked loop (SSPLL) stability often exacerbate spur degradation or incur excessive area overhead, rendering them unsuitable for high-resolution image sensor applications. This paper proposes a novel SSPLL based on capacitor multiplication technology. This capacitor multiplication technology employs dual charge pumps (CP1 and CP2) in a coordinated operational scheme where their charge/discharge states are inversely synchronized. The effective capacitance of the loop filter is thereby amplified without expanding the physical layout area dedicated to capacitive components. Meanwhile, the continued use of zero-compensation technology ensures the stability of the SSPLL. The proposed SSPLL is designed and verified in a 55 nm CMOS process. At a 1.2 GHz output frequency, simulation results show a spot phase noise of −131.5 dBc/Hz at 1 MHz offset, accompanied by an integrated RMS jitter of 549 fs across the 10 kHz to 40 MHz spectrum, spurs suppressed to −51.3 dB, while maintaining a power efficiency of 3.81 mW and a compact layout area of 0.064 mm2. All the above results show that by introducing the novel dual-CP charge multiplication technology, the SSPLL can achieve low jitter and low power consumption performance while reducing the layout area, providing a new technical approach for its application in high-resolution image sensors.
