GaAs MMIC Radar Sensors for Vital Sign Monitoring
活動簡介
Leveraging GaAs monolithic microwave integrated circuit (MMIC) technology, both self-injection-locked (SIL) and super-regenerative oscillator (SRO) architectures demonstrate exceptional capabilities for vital sign monitoring, characterized by high sensitivity and low power consumption. SIL radars offer simplified hardware design with substantial sensitivity, while SRO systems further enhance sensitivity while minimizing power consumption. Experimental results highlight the superior performance of these W-band integrated radars, underscoring their potential for precise healthcare monitoring applications.
Advancements in W-band SIL and SRO radar systems leveraging GaAs MMIC technology demonstrate significant improvements in sensitivity and system efficiency, making them well-suited for vital sign monitoring applications. SIL radars achieve high signal-to-noise ratio (SNR) without the need for a low-noise amplifier (LNA), while SRO radars offer superior sensitivity with lower power consumption and reduced system complexity. Both architectures emerge as promising candidates for next-generation healthcare monitoring systems. These innovations underscore the potential of mm-wave radar technology in enabling high-precision healthcare applications.
