Abstract

This paper presents an original method for the design of Bulk Acoustic Wave (BAW) filters for a new class of applications: ultra-low-power, narrow-band RF filtering. To this end, a filter co-design methodology, based on existing BAW resonator technology and fabrication processes, is developed and the link between decreasing filter bandwidth and decreasing power consumption of the associated integrated circuit is demonstrated. Depending on required bandwidth, the power dissipation of the driving electronics can be reduced by large factors (10 to 40). Applications to High-IF receivers and Wake-up receivers are described.
