“…To minimize the error signal V e , we must make the magnitude of L(s) large while still keeping the overall feedback loop nicely stable. However, architecting L(s) to achieve good stability margins is often made difficult due to little insights offered from the complicated expression of L(s) if solved directly from (6). Hence, in this work, we resort to the use of a graphical technique to help visualize different components of L(s) such that we can design different components to achieve a satisfactory L(s).…”

This paper presents the design of an output-capacitorless low-dropout voltage regulator (OCL-LDO) capable of driving a wide range of load capacitance and supplying a wide range of load current while maintaining excellent load and line regulations, thanks to the combined indirect-direct nested Miller compensation which ensures stability and maintains a high loop gain over the whole range of load condition. Fabricated in a 0.18-µm CMOS process and consuming 14 µA of quiescent current, the OCL-LDO, while supplying the load current between 0 mA to 100 mA, is capable of driving the load capacitance in the range of 0-1 nF; with a minimum load current of 1 mA, however, the OCL-LDO can drive up to 10 nF of load capacitance. Over such wide load-current and load-capacitance ranges, the OCL-LDO achieves DC load and line regulations of 0.025 mV/mA and 0.5 mV/V, respectively.INDEX TERMS output-capacitorless, low-dropout voltage regulator, wide load range, load regulation, line regulation, low-power regulator, Nested Miller Compensation, system-on-chips, power management circuits.

“…The modulation mode of passive UHF RFID is backscattered energy [51]. The principle of ASK backscatter modulation is to control the internal impedance of the electronic tag chip, so that the mismatch between the chip and the antenna indirectly changes the reflection coefficient.…”

Radio frequency identification (RFID) tags are widely used in various electronic devices due to their low cost, simple structure, and convenient data reading. This topic aims to study the key technologies of ultra-high frequency (UHF) RFID tags and high-precision temperature sensors, and how to reduce the power consumption of the temperature sensor and the overall circuits while maintaining minimal loss of performance. Combined with the biomedicine, an innovative high-precision human UHF RFID chip for body temperature monitoring is designed. In this study, a ring oscillator whose output frequency is linearly related to temperature is designed and proposed as a temperature-sensing circuit by innovatively combining auxiliary calibration technology. Then, a binary counter is used to count the pulses, and the temperature is ultimately calculated. We designed a relaxation oscillator independent of voltage and current. The various types of resistors were used to offset the temperature deviation. A current mirror array calibration circuit is used to calibrate the process angle deviation of the clock circuit with a self-calibration algorithm. This study mainly contributes to reducing power consumption and improving accuracy. The total power consumption of the RF/analog front-end and temperature sensor is 7.65 μW. The measurement error of the temperature sensor in the range of 0-60 ℃ is less than ±0.1%, and the accuracy of the output frequency of the clock circuit is ±2.5%.

The logistics traceability system can cover the whole process of the product from the source of production to the consumption cycle. By distinguishing the key nodes of the product in the logistics sales process, the data information of the production and storage of the corresponding product is collected and entered at the corresponding node, so that the entire process is visible and controllable. On the basis of determining the overall system plan, this paper designs and develops the UHF RFID reader system and traceability system platform. In terms of the reader system, by analyzing its core functions and performance index requirements, the overall design scheme and frame structure of the reader system’s software and hardware are determined. The main control circuit is based on the STM32F103RET6 single-chip microcomputer; the RF transceiver circuit is based on the MagicRF M100. Simultaneously, we design a variety of communication circuits including LoRa and RJ45 to facilitate wireless communication with the traceability platform. In terms of software, through the research and analysis of the EPC Class-1 Generation-2 protocol standard, the multitag anticollision algorithm—Q algorithm—is adopted. This algorithm has the advantages of high recognition efficiency and a large number of successfully recognized tags per unit time. According to the design plan, the system is wirelessly networked in the B/S mode and the product information collected through RFID technology is transmitted to the management level to dynamically understand the information dynamics of logistics in real time. Using radio frequency, computer network, communication, and other technologies, the hardware and software systems of the system are integrated. The performance indicators of the hardware system are tested through experiments, and the design indicators are compared to prove the feasibility of the equipment application. After setting up the local area network and configuring the server configuration, the traceability system was accessed and the verification of the basic functions of the system was completed. The test results show that the low-cost universal RFID wireless logistics terminal has high accuracy and real-time performance in the process of logistics traceability.
