A CMOS VCII-Based Multi-Waveform Generator with Reduced Harmonic Distortion

This paper presents a multi-stage waveform generator based on second-generation Voltage Conveyors (VCIIs). The proposed architecture enables the generation of multiple waveform types, including a sinusoid, a square wave, a triangular wave, and a reconstructed quasi-sinusoidal waveform. The system is designed using casc...

Theoretical research and verification on SAW multiplexer synthesis based on the COM model

As core components of radio frequency (RF) front-ends, surface acoustic wave (SAW) filters and duplexers rely on the acoustic wave propagation characteristics of piezoelectric materials, and have become particularly important, driven by the dual demands of multi-band compatibility and integration. However, the traditio...

Comparative Analysis of First-Order, Second-Order, and Fourth-Order Low-Pass Filters in Amplitude Modulation Synchronous Demodulation Systems

. Amplitude Modulation (AM) is both a ubiquitous modern communication technology and is used extensively in the low-power Internet of Things (IoT). In real-life settings, noise in a channel, system flaws, and electromagnetic interference are major factor that plagues the quality of communications, and this aspect requi...
