Jiang, J. (author), Chang, Z.Y. (author), Pertijs, M.A.P. (author)This paper presents an energy-efficient readout circuit for micro-machined resonant sensors. It operates by briefly exciting the sensor at a frequency close to its resonance frequency, after which resonance frequency and quality factor are determined from a single ring-down transient. The circuit employs an inverter-based trans-impedance...journal article 2015
