Simulation And Testing Of A High-Temperature Oscillator Circuit, Jude Zanoni
Honors College
A high-temperature Pierce oscillator circuit was designed, analyzed, simulated, built and tested. The oscillator was designed as part of a high-temperature sensor system for monitoring the condition of equipment operating in harsh environments. The oscillator was designed using a silicon carbide (SiC) metal-oxide-semiconductor field effect transistor (MOSFET) common source amplifier with an LC tank resonant circuit. It was manufactured using gold paste on alumina with 1 mil gold wire bonded between components. All components needed to be capable of operating at temperatures up to 400°C. To this end, high-temperature spiral planar inductors were designed and fabricated. These were found to …
