A Design of Analog PLL-Based Self-Calibrated Open-Loop FSK Modulator for BLE Advertising Transmitter

This brief presents a self-calibrated open-loop modulation technique for a Bluetooth low energy (BLE) advertising transmitter. The proposed technique can be implemented using a voltage-controlled oscillator (VCO), counter, and capacitor for voltage storage in an analog phase-locked loop (PLL). In th...
