Special Issue Information

Dear Colleagues,

Sensors are widely utilized in a variety of applications, including those in healthcare, transportation, consumer electronics, and industry. That demand raises the bar for sensor circuit quality and intelligence. Digital-aware or software-aware sensor circuits are on the design agenda in the age of digital technology. The Internet-of-Things (AI-IoT), which is emerging as one of the driving factors in the industry, has presented additional design criteria and limits to the interface circuits that aim to improve sensors' detection capabilities with the help of AI. It seems that the interface circuits, which may be coupled with intelligent peripheral support circuits, can provide cutting-edge features to fulfill high-performance-aware standards or high-adaptability, etc., and thus actualize smart functions through smart program control.

The objective of this Special Issue is to envisage future research directions through academicians, researchers, engineers, and industrial participants to share their research findings with global experts. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • AI-IoT sensor circuit design and techniques;
  • Data communication for sensor circuits;
  • Digital-assisted sensor circuits;
  • Energy-efficient networking;
  • GHz-to-THz frequency radiation;
  • Intelligent peripheral circuits for sensor circuits;
  • Low-power and UWB radios for communication and ranging;
  • mm-wave and sub-6GHz receivers and transceivers for 5G radios;
  • mm-wave and sub-THz ICs for communication and sensing;
  • Sensor circuits with configurable architectures;
  • Smart power management circuits for sensors;
  • Smart sensor systems;
  • Software for sensor circuits;
  • Wireless-powered communication.

We look forward to receiving your contributions.

The proliferation of radar technology has given rise to a growing demand for advanced, high-performance transmitter front-ends operating in the 24 GHz frequency band. This paper presents a design analysis of a radio frequency (RF) transmitter (TX) front-end operated at a 24 GHz frequency and designed using 65 nm complementary metal-oxide-semiconductor (CMOS) technology for radar applications. The proposed TX front-end design includes the integration of an up-conversion mixer and power amplifier (PA). The up-conversion mixer is a Gilbert cell-based design that translates the 2.4 GHz intermediate frequency (IF) signal and 21.6 GHz local oscillator (LO) signal to the 24 GHz RF output signal. The mixer is designed with a novel technique that includes a duplex transconductance path (DTP) for enhancing the mixer’s linearity. The DTP of the mixer includes a primary transconductance path (PTP) and a secondary transconductance path (STP). The PTP incorporates a common source (CS) amplifier, while the STP incorporates an improved cross-quad transconductor (ICQT). The integrated PA in the TX front-end is a class AB tunable two-stage PA that can be tuned with the help of varactors as a synchronous mode to increase the PA bandwidth or stagger mode to obtain a high gain. The PA is tuned to 24 GHz as a synchronous mode PA for the TX front-end operation. The proposed TX front-end showed an excellent output power of 11.7 dBm and dissipated 7.5 mW from a 1.2 V supply. In addition, the TX front-end achieved a power-added efficiency (PAE) of 47% and 1 dB compression point (OP1dB) of 10.5 dBm. In this case, the output power is 10.5 dBm higher than the linear portion of the response. The methodologies presented herein have the potential to advance the state of the art in 24 GHz radar technology, fostering innovations in fields such as autonomous vehicles, industrial automation, and remote sensing.

On account of active governmental stimulation operations in many countries, the residential production of electricity from renewable resources has increased considerably. Due to high efficiency and reliability, a recommended solution for residential wind energy conservation systems (WECS) is permanent magnet synchronous generators (PMSG). A higher torque ripple (TR), engendered by the contact of the stator with the rotor’s magnetomotive force harmonics, is one foremost issue in PMSGs. To control the synchronous generator, numerous control schemes have been proposed. However, it still faces a challenge in the diminishment of the TR. An enhanced fuzzy logic controller (EFLC) in interior PMSG (IPSMG) under variable wind speed (WS) has been proposed in this article to address this challenge. Initially, the wind turbine (WT) system was designed, and the IPMSG was proposed. A hysteresis controller (HC) and fuzzy logic controller (FLC) are the two controller types utilized in this model to control TR. This methodology used the EFLC to eliminate errors during the control. By using the proper membership function (MF) for boundary selection in the WDCSO algorithm, an enhancement was executed. Better performance in TR reduction was attained by the proposed model grounded in the analysis. Full article
