Assignee: SITIME CORPORATION
Field: Basic communication processes (Electrical engineering)
Classification: CPC H  B | IPC B  H

Claim 0:
1. An integrated circuit comprising:
a first die having a microelectromechanical systems (MEMS) resonant structure;
a second die having at least one transistor;
a third die having circuitry; and
the integrated circuit further comprising a heating element, a sensor, a thermally-conductive element and an insulator, the sensor to sense a temperature experienced by the first die and the second die, the heating element to raise the temperature experienced by the first die and the second die to a predetermined temperature that is different than a temperature of an ambient environment external to said integrated circuit, the insulator to insulate the third die from experiencing the predetermined temperature, the thermally-conductive element coupling the third die with the ambient environment, so as to urge the third die toward the temperature of the ambient environment;
wherein the integrated circuit is to output, via an external contact of said integrated circuit, a timing signal, the timing signal being dependent on a frequency of resonant motion of the MEMS resonant structure, the timing signal generated using each of the at least one transistor of the second die and the circuitry of the third die.
