The world's first single-chip RF transceiver to support 5G sub-6-GHz new radio (NR) and
long-term evolution (LTE) E-UTRA New Radio-Dual Connectivity (EN-DC) in 14-nm FinFET …

This article presents a highly programmable time-approximation filter (TAF) that can be
embedded in a direct RF transmitter architecture. The proposed filter technique …

The digital front-end of the communication transceivers envisioned for fifth-generation (5G)
and beyond requires highly configurable high-performance digital signal processing (DSP) …

Along with increasingly high number of connected devices and data explosion, the
emerging 802.11 ax promises elevated throughput and spectral efficiency by introducing …

This paper presents a 680 MHz-6 GHz 2 x 2 multiple-input and multiple-output (MIMO) long-
term evolution (LTE) RF transceiver in 65-nm CMOS for low-cost and multi-band capable …

A ax transceiver design is presented to support dual-band simultaneous operation (DBS)
and 1024-QAM modulation. The proposed architecture features linearity enhancement for …

The role that the cellular phone plays in our daily lives is constantly evolving. Conceived as
a" mobile" telephone to contrast with a" tethered" telephone, the cell phone functions as a …

We present the first all-digital LTE transmitter (TX) using programmable digital attenuation of
receive band (RX-band) noise. The system is architectured to fully exploit the speed and low …

This paper presents a single-bit RF transmitter based on single-bit switched-capacitor RF
digital-to-analog converters (DACs) embedded in an finite-impulse response (FIR) filter (FIR …

To impose the reconfigurability and reusability of digital circuits for millimeterwave
transmitter architectures, high-speed digital signal processing architectures are explored …
