Author(s): Thinh Tran-Dinh, Hafiz Usman Mahmood, Jinglong Xu, Keun-Mok Kim, Kyung-Sik Choi, Jaeheon Lee, Jinho Ko, Sang-Gug Lee, Jusung Kim

Abstract:

This letter presents a multiband fully integrated ultralow-power (ULP) transceiver with a two-step wake-up receiver (WuRX) and switched-capacitor (SC)-based high-efficiency transmitter. Operating from 200 MHz to 1 GHz, the transceiver covers most IoT applications on a single chip. By employing a novel two-step wake-up scheme with a rotating correlator, the proposed …

A Fully Integrated Galvanic Isolator for Gate Drivers With Asynchronous 100/167 Mb/s ASK/FSK Full-Duplex Communication

A Fully Integrated Galvanic Isolator for Gate Drivers With Asynchronous 100/167 Mb/s ASK/FSK Full-Duplex Communication 150 150

Abstract:

A fully integrated galvanic isolator for gate drivers that supports high-speed, asynchronous, full-duplex communication is presented. Data transmission from the microcontroller to the power device is achieved using amplitude-shift keying (ASK) at 100 Mb/s, while simultaneous communication in the opposite direction is implemented using frequency-shift keying (FSK) at 167 Mb/s. …
