In this work, we present an open-source fully-synthesizable fractional-N all-digital phase-
locked loop (ADPLL) designed for a Bluetooth low-energy (BLE) transmitter (TX) along with …

A novel digital-intensive hybrid transmitter (TX) architecture is presented, combining
conventional inphase and quadrature (I/Q) with constrained phase modulation. The …

The present disclosure includes Switched capacitor trans mitter circuits and methods. In one
embodiment, a digital data signal is thermometer encoded and a negative thermo encoded …

This article presents a novel digital predistortion (DPD) approach to compensate for
nonlinear dynamic distortions caused by the supply network of capacitive radio frequency …

In this paper, a linear model for intrinsic power and efficiency in Radio-Frequency Switched-
Capacitor Power Amplifiers (SCPA) is presented. Given a target output power and frequency …

In this paper a state-space approach for modeling radio-frequency digital-to-analog-
converters is presented. We explain the root cause of the sign-change error appearing in RF …

In this paper, an overview of different RF transmitter architectures, based on the RF-DAC
implementation is given. The evolution of different types of architectures is displayed with the …

Detailed state-space modeling and analysis of a class of RF switched-capacitor power
amplifiers achieving high efficiency, output power, and linearity are presented. Time-domain …

In this article, we comprehensively investigate the potential of the digital polar radio
transmitter architecture for multi-user massive multiple-input multiple-output orthogonal …

The present disclosure includes Switched capacitor trans mitter circuits and methods. In one
embodiment, the present disclosure includes a plurality of Switched capacitor trans mitter …
