摘要: A MEMS resonator system comprises a MEMS resonator, kick start circuitry, feedback circuitry, an oscillator, and a switch. The MEMS resonator system is configured to provide a pulsed kick-start signal having a frequency and period such that energy delivered to the MEMS resonator is optimized in a short period of time, resulting is reduced oscillator startup time. The MEMS resonator system is configured to switch out the kick-start signal when the MEMS resonator oscillation has been achieved, and switch in feedback circuitry to maintain the MEMS resonator in a state of oscillation.

摘要: An electrically alterable circuit (EAC), suitable for use in an integrated circuit, includes a first interconnect, a link element, and a second interconnect. A first set of interconnect vias provides an electrically conductive connection between the first interconnect and a first end of the link element; A second set of interconnect vias provides an electrically conductive connection between the second interconnect and a second end of the link element. The EAC further includes a third interconnect and a one or more fuse vias that provide an electrical connection between the third interconnect and the link element. A conductance of the one or more fuse vias is less than a conductance of the first set of interconnect vias, a conductance of the second set of interconnect vias, or both.

摘要: A multi-die sensor system comprises a package and one or more transducer dies mounted in the package. Each transducer die includes one or more transducers, a temperature control element, and temperature sensor. The temperature control element changes the temperature of at least a portion of the transducer during operation of the temperature control element. A temperature sensor senses the temperature of at least the portion of the transducer. An output circuitry die mounted in the package receives transducer signals and a sensed temperature signal from the temperature sensor.

摘要: A semiconductor die (20) includes a substrate (30) and microelectronic devices (22, 26) located at a surface (32) of the substrate (30). A cap (34) is coupled to the substrate (30), and the microelectronic device (22) is positioned in the cavity (24). An outgassing material structure (36) is located within a cavity (24) between the cap (34) and the substrate (30). The outgassing material structure (36) releases trapped gas (37) to increase the pressure within the cavity (24) from an initial pressure level (96) to a second pressure level (94). The cap (34) may include another cavity (28) containing another microelectronic device (26). A getter material (42) may be located within the cavity (28). The getter material (42) is activated to absorb residual gas (46) in the cavity (28) and decrease the pressure within the cavity (28) from the initial pressure level (96) to a third pressure level (92).

摘要: A MEMS device (20) includes a movable element (20) suspended above a substrate (22) by a spring member (34) having a spring constant (104). A spring softening voltage (58) is applied to electrodes (24, 26) facing the movable element (20) during a powered mode (100) to decrease the stiffness of the spring member (34) and thereby increase the sensitivity of the movable element (32) to an input stimulus (46). Upon detection of a stiction condition (112), the spring softening voltage (58) is effectively removed to enable recovery of the movable element (32) from the stiction condition (112). A higher mechanical spring constant (104) yields a stiffer spring (34) having a larger restoring force (122) in the unpowered mode (96) in order to enable recovery from the stiction condition (112). A feedback voltage (56) can be applied to feedback electrodes (28, 30) facing the movable element (32) to provide electrical damping.
