    Abstract: A single-axis tilt-mode microelectromechanical accelerometer structure. The structure includes a substrate having a top surface defined by a first end and a second end. Coupled to the substrate is a first asymmetrically-shaped mass suspended above the substrate pivotable about a first pivot point on the substrate between the first end and the second end and a second asymmetrically-shaped mass suspended above the substrate pivotable about a second pivot point on the substrate between the first end and the second end. The structure also includes a first set of electrodes positioned on the substrate and below the first asymmetrically-shaped mass and a second set of electrodes positioned on the substrate and below the second asymmetrically-shaped mass.

    Abstract: An apparatus and method of testing one-time-programmable memory provides one-time-programmable memory having one or more memory locations for storing data and corresponding programming circuitry for each memory location. In addition, each programming circuitry has a circuit element configured to permanently change state to store the data in the memory. The method also reads each memory location to verify that the memory location is unprogrammed and activates the programming circuitry for each memory location, which applies a test current to the programming circuitry. The test current is less than a threshold current needed to permanently change the state of the circuit element. The method then determines whether the programming circuitry is functioning properly.

    Abstract: According to some aspects, a low-leakage switch is provided. In some embodiments, the low-leakage switch includes a plurality of pass transistors in series that selectively couple two ports of the low-leakage switch and a node biasing circuit coupled to a node between the plurality of pass transistors. In these embodiments, the node biasing circuit may adjust a voltage at the node to change the gate-to-source voltage of the pass transistors and, thereby, reduce the leakage current through the pass transistors when the low-leakage switch is turned off. The node biasing circuit may also include circuitry to reduce the leakage current introduced by the node biasing circuit into the node when the low-leakage switch is turned on.

    Abstract: A state of one or more fuses can be determined using a common-gate FET device to read reference information and test information from a fuse bank. In an example, the FET device can be selectively diode-connected using a first switch that responds to a control signal, and a signal-storing capacitor can be connected to the gate terminal of the FET device. The capacitor can store information about a reference signal when the first switch is closed and a first input signal is applied at a source node of the FET device. When the first switch is open, a second input signal can be applied at the source node of the FET device, and an output signal at the drain node of the FET device can indicate a magnitude relationship between the first input signal and the reference signal. In an example, the second input signal can indicate a state of a fuse.

    Abstract: An amplifier system has an amplifier for amplifying a plurality of input signals from a plurality of different channels, and a plurality of demodulators each operatively coupled with the amplifier for receiving amplified input signals from the amplifier. Each demodulator is configured to demodulate a single amplified input channel signal from a single channel of the plurality of different channels. The system thus also has a plurality of filters, coupled with each of the demodulators, for mitigating the noise.
