Special Issue Information

Dear Colleagues,

RF/Microwave are terms used to describe electromagnetic (EM) waves with frequencies ranging from 300 kHz to 300 GHz. This frequency range corresponds to free space wavelengths from 1 km to 1 mm. EM waves with frequencies ranging from 30 to 300 GHz are commonly known as millimeter waves because their wavelengths fall above 1 mm and below 10 mm. The radio frequency (RF) spectrum with a range of 300 k–30 G Hz lies below the microwave spectrum. However, the boundary between the RF and microwave spectra is arbitrary and depends on the technology developed for the exploitation of the specific spectrum.

This Special Issue focuses on recent developments in the analysis, design, implementation and measurement of RF, microwave and millimeter-wave integrated circuits, including (but not limited to) wireless transceivers (transmitters and receivers) and their submodules, such as RF amplifiers, mixers, phase-locked loops, filters, diplexers/multiplexers, power dividers/combiners, couplers/transformers, phase shifters, etc., for modern communication systems. Recent advancements in the AI-based automatic design of RF circuits, such as machine learning and optimization techniques for the automated design, simulation, and layout generation of RF amplifiers, mixers, and phase-locked loops, are also welcome. Authors are invited to submit their latest research findings (including simulation and measurement results) for publication. Both regular articles and review papers are welcome.

A high-efficiency frequency multiplier is presented in 65-nm CMOS with a core area of 0.06 mm2. A low-cost five-segment triangular-resistance phase interpolation scheme is proposed. By performing resistive interpolation on four-path orthogonal triangular signals, 10-fold frequency multiplication is achieved within the input frequency range of 12–20 MHz. The prototype only includes a quadrature square-wave generator, four orthogonal square-triangular converters and the proposed four-path 5-segment triangular-resistance phase interpolators, with a frequency deviation less than 7%. The presented design achieves an output power of −9.8 dBm, with an input power of −2.0 dBm and power consumption of 0.45 mW from a 1.2-V supply, which obtains a frequency multiplication efficiency up to 9.6%. The proposed mechanism could be extended to accomplish a configurable multiplication factor. Full article
