Special Issue Information

Dear Colleagues,

Analog and radiofrequency (RF) circuit design remains a cornerstone of modern electronics, enabling critical functionality in applications ranging from wireless communication and sensor interfaces to biomedical systems and high-performance computing. As digital systems continue to scale and diversify, the demand for robust, power-efficient, and high-performance analog and RF front ends is greater than ever.

Recent advances in circuit design methodologies, device modeling, and system-level integration have opened up new possibilities for performance optimization, noise reduction, bandwidth extension, and ultra-low-power operation. At the same time, emerging application areas such as 6G communications, quantum systems, wearable health monitoring, and automotive radar are driving innovation in analog/RF design far beyond the traditional paradigms.

This Special Issue aims to present the latest progress in analog and RF circuit design, with an emphasis on novel architectures, design techniques, modeling approaches, and circuit implementations. We invite submissions that address challenges and breakthroughs in the design of low-noise amplifiers, mixers, power amplifiers, phase-locked loops, data converters, and other key building blocks, particularly in the context of system integration and real-world application. Topics of interest include, but are not limited to the following:

  • Analog and RF circuit design;
  • Data converters, phase-locked loop, voltage-controlled oscillator, and sensor interface circuit;
  • Low-noise amplifier and mixer and power amplifier;
  • Key building blocks for analog/RF circuits;

I look forward to receiving your contributions.

Improving the transient response performance is a critical challenge in low-dropout regulator (LDO) design. This paper proposes a novel on-chip capacitor-less LDO based on substrate technology implemented in an SMIC (Semiconductor Manufacturing International Corporation) 0.18 μm CMOS (complementary metal oxide semiconductor technology) process. Central to this innovation is a fast response loop between the PMOS driver’s body and gate, which leverages the body effect to enhance driver control without complex bulk-driven techniques. The proposed LDO achieves a quiescent current of 4.5 μA, an efficiency of 88%, an overshoot/undershoot of 12mV/22mV, and a settling time of 1.2 μs. The comparative analysis confirms that this structure increases the maximum load current and reduces the loop response time relative to those for conventional LDOs. These results validate a significant improvement in the transient performance, marking an important advance in integrated voltage regulator technology. Full article
