TL;DR: A resistor-based frequency-tuning scheme helps in mitigating odd-order harmonic distortion induced by the VCO nonlinear transfer characteristic and provides a reconfigurable input range in a 0.2-V open-loop voltage-controlled oscillator (VCO)-based analog-to-digital converter intended for IoT wireless sensor nodes.

TL;DR: A novel approach for built-in self-testing (BIST) of an RF wireless transmitter that allows the testing of the transmitter's analog/RF circuitry while providing low-cost replacements for the costly traditional RF tests.

TL;DR: This work addresses all problems of the first-ever all-digital PLL and demonstrates RF performance matching that of the best-in-class traditional approaches.

TL;DR: In this paper, an integrated circuit comprises a digitally-controlled power generation stage (DPA) for converting an input signal to a radio frequency (RF) carrier, the DPA comprising a plurality of selectable switching devices capable of adjusting an envelope of the RF carrier; and a pulse width modulator (PWM) generator arranged to generate a PWM control signal and operably coupleable to the plurality of selected switch devices.

TL;DR: The harmonic distortion results obtained in the context of the proposed characterization technique effectively highlight the performance of the polar transmitter when it is driven with the wideband baseband envelope and phase-modulating signals of today's high-data-rate digital communication systems, such as wideband code-division multiple access and beyond.
