A Low-Power 10Mbps Squaring-First UWB Receiver Using Frequency Hopping and Two-Tone Modulation 150 150

Abstract:

This paper presents a low-power 10Mbps squaring-first ultra-wideband (UWB) receiver using frequency hopping code-division multiple-access (FH-CDMA) and two-tone OOK modulation for wireless personal area networks (WPAN). The two-tone receiver architecture preserves IF filtering, improves resilience to narrowband interference, and saves power by eliminating the RF local oscillator. FH is applied …

Design and Analysis of a 13.7–41 GHz Ultra-Wideband Frequency Doubler With Cross-Coupled Push-Push Structure

Design and Analysis of a 13.7–41 GHz Ultra-Wideband Frequency Doubler With Cross-Coupled Push-Push Structure 150 150

Abstract:

This article presents a 13.7–41 GHz ultra-wideband frequency doubler with high efficiency and conversion gain (CG). The proposed cross-coupled push-push structure, in conjunction with the fourth-order transformer-based resonator and the series gate inductor, collaboratively shapes the input signal amplitude such that three distinct peaks emerge at different frequencies, thereby significantly improving …
