Abstract:

This article introduces a high-resolution continuous-time delta–sigma modulator (CT DSM) architecture that incorporates a successive approximation register (SAR)-assisted digital noise coupling (DNC) technique and a multi-stage noise-shaping (MASH) structure. The limited maximum stable amplitude (MSA) problem due to the high-order-shaped large quantization error ( $Etextsubscript{1}$ ) in the previous …

A Multichannel Injection-Locked OOK Transmitter With Current Mode Edge-Combining Power Amplifier
A Multichannel Injection-Locked OOK Transmitter With Current Mode Edge-Combining Power Amplifier 150 150
Author(s): Sheng-Kai Chang, Zhi-Wei Lin, Kuang-Wei Cheng

Abstract:

This letter introduces an ultralow-power ON–OFF keying (OOK) wireless transmitter incorporating innovative multiphase injection locking and frequency multiplication techniques. The transmitter leverages a current mode class-D edge-combining power amplifier, ensuring high-energy efficiency in frequency multiplication to generate the carrier frequency. With a primary focus on facilitating multichannel support for …
