摘要： A bulk acoustic wave resonator comprising a substrate (5), a Bragg reflector (4), a top (1) and a bottom (3) electrode and a piezoelectric layer (2) with means for suppression of the pass-band ripples in a bulk acoustic wave filter. The means for absorbing or scattering the spurious modes are a roughened rear side of the substrate (6), an absorbing layer (5) disposed on the rear side of the substrate (6) and/or an absorbing layer (5) disposed on the front side of the substrate.

摘要： A method of, and apparatus for, obtaining a representation of an electrical circuit (400) suitable for time-domain simulation. The electrical circuit comprises a physical structure (102), which is modelled using electromagnetic field analysis, and also comprises a remainder circuit (104) of circuit components which are interconnected with the physical structure. The electromagnetic field analysis is capable of generating at least a high-frequency equivalent circuit which is representative of the physical structure (102) and is valid at the operating frequency of the circuit but not at DC. The method comprises including a set of DC sources (E1 to Ek) to ensure that, in a time-domain simulation, improved DC bias conditions are provided for any non-linear components in the remainder circuit. The DC sources may be voltage sources in each interconnection, current sources between each interconnection and a zero voltage reference interconnection, or a combination of the two.
