Classification: CPC H | IPC H

Claim 12:
13. The device of claim 7 wherein:
the piezoelectric material layer of the body is characterized by a first first-order temperature coefficient of frequency (TCF) and a first second-order TCF;
the first degenerately doped silicon layer of the body is characterized by a second first-order TCF and a second second-order TCF;
the second degenerately doped silicon layer of the body is characterized by a third first-order TCF and a third second-order TCF;
the body is structured such that a sum of the first first-order TCF, the second first-order TCF and the third first-order TCF is substantially equal to a target value at a predetermined temperature; and
the body is structured such that a sum of the first second-order TCF, the second second-order TCF and the third second-order TCF is substantially equal to a target value at the predetermined temperature.
