Abstract
An acoustic resonator circuit to be integrated into a semiconductor product including: a resonator comprising first and second resonant frequencies; an inductive resistor tuned to said second resonant frequency so as to cancel the latter and to allow tuning of the resonator to said first resonant frequency; an tunable capacitive tuning element allowing to tune the resonator to said first frequency. A method is also provided for manufacturing an integrated circuit comprising an acoustic component allowing sufficient control of resonator characteristics.
