Analysis of the “Push–pull” Capacitance Bridge Circuit for Comb-Drive Micro-electro-mechanical Oscillators

We have developed an improved actuation/detection scheme for a comb-drive micro-electro-mechanical oscillator as a probe to study quantum fluids. This symmetric scheme has many advantages over the asymmetric scheme used previously. In this report, we provide a full description and analysis of the me...

Summary:We have developed an improved actuation/detection scheme for a comb-drive micro-electro-mechanical oscillator as a probe to study quantum fluids. This symmetric scheme has many advantages over the asymmetric scheme used previously. In this report, we provide a full description and analysis of the method so that researchers interested can readily implement the method in their experiments involving similar devices.
