Abstract: In a timing signal generator having a resonator, one or more temperature-sense circuits generate an analog temperature signal and a digital temperature signal indicative of temperature of the resonator. First and second temperature compensation signal generators to generate, respectively, an analog temperature compensation signal according to the analog temperature signal and a digital temperature compensation signal according to the digital temperature signal. Clock generating circuitry drives the resonator into mechanically resonant motion and generates a temperature-compensated output timing signal based on the mechanically resonant motion, the analog temperature compensation signal and the digital temperature compensation signal.

Abstract: An oscillator includes a resonator, sustaining circuit and detector circuit. The sustaining circuit receives a sense signal indicative of mechanically resonant motion of the resonator generates an amplified output signal in response. The detector circuit asserts, at a predetermined phase of the amplified output signal, one or more control signals that enable an offset-reducing operation with respect to the sustaining amplifier circuit.

Abstract: In an integrated circuit device having a microelectromechanical-system (MEMS) resonator and a temperature transducer, a clock signal is generated by sensing resonant mechanical motion of the MEMS resonator and a temperature signal indicative of temperature of the MEMS resonator is generated via the temperature transducer. The clock signal and the temperature signal are output from the integrated circuit device concurrently.
