“…It offers a smaller size by eliminating the requirement of big size capacitors in the filter, process, temperature and voltage (PVT) variations independence, and flexibility in programming and control. [2], [3] Beginning of ADPLL started in 1980. [4] The studies reveal that ADPLL outperforms classical PLLs and have more significance towards communication systems as well as consumer applications.…”

Nowadays control applications play a major role in different applications such as industrial automation, robotics, automobiles, power systems etc. The all-digital phase-locked loop (ADPLL) is a digital controller can be used commonly for all kind of control applications based on the application requirement. In the work, KGMO based ADPLL is proposed to perform the rotation control of an induction motor (KGMO-ADPLL-IMSC) under various load conditions by the varying current. The proposed ADPLL is tested in an induction motor (IM) to control the rotation of the motor under certain load conditions. Various parameters such as speed, torque, phase, amplitude and offset values are considered to generate the control signal. Root mean square error (RMSE) is considered as the objective function for the KGMO algorithm. Least error is considered for the best fitness function for the better performance. In this work, the current control technique is used to perform the rotation control of the induction motor. Various performance such as torque, speed and stability are measured under various load conditions. KGMO-ADPLL-IMSC design is implemented in an integrated MATLAB/SIMULINK environment under various inbuild and custom libraries. Experiments show that the KGMO-ADPLL-IMSC strategy is altogether improved the performance in terms of all performance evaluation graphs

“…However, this paper proposes a high-gain, low-noise, low-power RF-FE that can only use an inductor-less low noise transconductance amplifier (LNTA) structure with LO of 25% duty ratio. Because the BBA operates at low power, the characteristics of the filter are sensitive to process, voltage, and temperature variations [7]. In this paper, we propose a Filter Tuning Circuit (FTC) to keep the cut-off frequency and bandwidth of the filter constant.…”

“…External components such as inductor and capacitor for impedance matching, baluns, and a transmitter (TX) as well as a receiver (RX) switch can increase system cost and be area consuming on the PCB. Therefore, it is beneficial to design the BLE RF transceiver that can interface directly with a single-ended 50-Ω antenna minimizing external components [7]. In this work, Single-Pole Double-Throw (SPDT), internal matching components, and Power Management Unit (PMU) such as the DC-DC buck converter and Low Drop-Outs (LDO) are integrated to reduce system cost.…”

This paper presents a low power Gaussian Frequency-Shift Keying (GFSK) transceiver (TRX) with high efficiency power management unit and integrated Single-Pole Double-Throw switch for Bluetooth low energy application. Receiver (RX) is implemented with the RF front-end with an inductor-less low-noise transconductance amplifier and 25% duty-cycle current-driven passive mixers, and low-IF baseband analog with a complex Band Pass Filter(BPF). A transmitter (TX) employs an analog phase-locked loop (PLL) with one-point GFSK modulation and class-D digital Power Amplifier (PA) to reduce current consumption. In the analog PLL, low power Voltage Controlled Oscillator (VCO) is designed and the automatic bandwidth calibration is proposed to optimize bandwidth, settling time, and phase noise by adjusting the charge pump current, VCO gain, and resistor and capacitor values of the loop filter. The Analog Digital Converter (ADC) adopts straightforward architecture to reduce current consumption. The DC-DC buck converter operates by automatically selecting an optimum mode among triple modes, Pulse Width Modulation (PWM), Pulse Frequency Modulation (PFM), and retention, depending on load current. The TRX is implemented using 1P6M 55-nm Complementary Metal–Oxide–Semiconductor (CMOS) technology and the die area is 1.79 mm2. TRX consumes 5 mW on RX and 6 mW on the TX when PA is 0-dBm. Measured sensitivity of RX is −95 dBm at 2.44 GHz. Efficiency of the DC-DC buck converter is over 89% when the load current is higher than 2.5 mA in the PWM mode. Quiescent current consumption is 400 nA from a supply voltage of 3 V in the retention mode.
