  • Abstract
    This paper addresses effects of constant voltage and current biasing methods on sensing bandwidth of electrothermal displacement sensors in micro-electromechanical systems (MEMS). The dynamic response of the sensor is modeled based on first principles. The obtained model successfully captures a variety of nonlinear phenomena. Experiments are conducted to confirm the validity of the model and simulation results.
