Title:
METHOD AND APPARATUS FOR UPCONVERTING AND FILTERING AN INFORMATION SIGNAL UTILIZING A VIBRATING MICROMECHANICAL DEVICE
Document Type and Number:
WIPO Patent Application WO2001082475
Kind Code:
A3
Abstract:
Several MEMS-based architectures which utilize vibrating micromechanical resonators in circuits to implement filtering, mixing, frequency reference and amplifying functions are provided. A method and apparatus are provided for upconverting and filtering an information signal utilizing a vibrating micromechanical device based on an AC signal having a desired frequency. One of the primary benefits of the use of such architectures is a savings in power consumption by trading power for high selectivity (i.e., high Q). Consequently, the present invention relies on the use of a large number of micromechanical links in SSI networks to implement signal processing functions with basically zero DC power consumption.
