这项工作报告的发展控制电子谐振模式生物传感器。实验室演示的传感器最初显示出-100 dB的信噪比。通过应用半频驱动、下变频、适当的滤波和数字信号处理，这一经济高效的电子解决方案可实现+30 dB的信噪比。本文重点介绍了基于微机电系统的传感器集成解决方案设计中的重要方面。
This work reports on the development of control electronics for a resonant mode biosensor. The laboratory demonstrated sensor initially showed a signal-to-noise ratio of -100 dB. With the application of half-frequency drive, frequency down conversion, appropriate filtering, and digital signal processing, a cost-effective electronic solution demonstrated a signal-to-noise ratio of +30 dB. This paper highlights important aspects in the design of integrated solutions to microelectromechanical systems-based sensors.
