We propose a time-predictive architecture of an all-digital PLL (ADPLL) for cellular radios, which is optimized for advanced CMOS. It is based on a 1/8-length time-to-digital converter (TDC) of stabilized 7-ps resolution, as well as wide tuning range, and fine-resolution class-F digitally controlled oscillator (DCO) with only switchable metal...

We present an ultra-low-power Bluetooth low-energy (BLE) transceiver (TRX) for the Internet of Things (IoT) optimized for digital 28-nm CMOS. A transmitter (TX) employs an all-digital phase-locked loop (ADPLL) with a switched current-source digitally controlled oscillator (DCO) featuring low frequency pushing, and class-E/F<sub>2</sub>...
