A second harmonic based resonance characterization method for MEMS electrostatic resonators

Ozge Zorlu, Mustafa Kangül

This paper presents a novel read-out approach both for eliminating parasitic feedthrough current and for enhancing the quality-factor (Q) of the resonating system at the same time. A new resonance characterization method based on sensing second harmonic co ...
