Abstract :
A micro-power tunnel-diode-based LC-tuned oscillator architecture is proposed for MEMS sensing and wireless data transmission applications. The prototype sensing and transmitting module employs a MEMS capacitive pressure sensor performing pressure to frequency conversion and a miniature on-board loop serving as the inductor for the LC tank and also a transmitting antenna. The system achieves a reliable telemetry performance over a distance of three meters with a total power consumption of 65 μW
