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.

IoT has numerous applications; in which oneof them is solar power tracking and modulating network. Energy saving mechanism can be delineated in IoT, which can lessen both energy dissipation and human endeavor necessary to do the task. The proposed system has been rendered to accord the PWM based solar charge controller and its response by utilizing webservers and the laptops/cell phones. The gadget has been used is W5100, the web server which will be accumulated on W5100 module is employed as an IoT platform. As webservers are unconstrained of platforms, they can be adoptable in cell phones/ laptop which is instructed by the relays and sequentially webservers compute the solar charge controllers through W5100 module. The proposed system deals with solar power tracking and sends the information to laptop/cell phone with the help of web servers for energy lessening. The proposed system is capable of identifying the battery charging conditions under different circumstances whenever needed and can be further upgraded to track other utensils. There are diverse modules utilized in solar charge controller circuit which makes it as an IoT based device like Arduino Ethernet shield (W5100), Atmega328p, solar panel, battery, which is hugely cost-effective and also low energy utilization.
