The performance of traditional wireless receivers is limited in a large part by the lack of a narrow bandwidth, low loss, and reconfigurable filter at the RF bandwidth, which leads to designers needing to use circuit techniques to ensure adequate linearity and allow channel selection. This project aims to make use of recent developments in high quality micromechanical resonators to enable new circuit designs featuring ultra-low power consumption and an extremely small size. The receiver will be based around an array of filters to perform sub-carrier separation and allow a multi-tone, OFDM-like, signal to be received in the analog domain using extremely low power, simple receivers, enabling reliable and flexible wireless reception.
