The purpose of system is using an electromagnetic sensor based on radar technologies to detect the motions of the vocal organs. The first subject is to design power detectors for this homodyne radar circuits. Two power detectors were designed and realized either in hybrid or monolithic way. The hybrid power detector was designed at 915 MHz based on lumped elements loaded with Schottky diodes. Additionally, it has been employed into an auto-level-control (ALC) circuit application. The monolithic power detector, which was fabricated by TSMC 0.18μm CMOS process, is a single-chip logarithmic amplifier that also can be used to detect the power. The other subject of this work is to develop a LabVIEW program for data acquisition and signal processing. The signals coming from both the microphone and the electromagnetic glottal micro-movement detection system were acquired and transferred into digital form for further analysis.
