    Abstract: A digital input to a digital-to-analog converter (DAC) is divided into a most significant portion and a lesser significant portion. At least one tap voltage generator generates a plurality of voltages, preferably using a resistor string. A decoder decodes at least one subword that forms the lesser significant portion to generate a corresponding at least one control signal. A switching unit accesses voltages generated by the at least one tap voltage generator in response to the at least one control signal. A scaled current generator generates a respective weighted current from each accessed voltage. An output stage combines all the weighted currents with a voltage that is an analog representation of the most significant portion of the digital input to generate an analog approximation of the entire digital input.

    Abstract: Integrated crash and vehicle movement sensing by use of distributed new multi-axis satellite sensors (302, 304, 306) combines side and/ or front/rear crash sensing with other applications requiring dynamic vehicle movement data like (but not limited to) roll and/or pitch detection as well as active suspension, head light beam levelling, etc. Depending on the required functionality, two or more satellite sensor modules (302, 304, 306) are used, which measure multi-axis high-g and low-g acceleration, without needing any further sensor inputs like gyroscopes while achieving a high level of failsafe and redundancy.

    Abstract: An integrator system may have a pair of sampling circuits each having a sampling capacitor to sample a respective component of a differential input signal, and an integrator having inputs coupled to outputs of the sampling circuits. The system may have a shorting switch coupled between input terminals of the sampling capacitors. The shorting switch may be engaged during an interstitial phase between sampling and output phases of the sampling circuits. By shorting input terminals of the sampling capacitors together, the design reduces current drawn by the system and, in some designs, severs relationships between current draw and information content sampled by the system. Configurations are disclosed for analog and digital input signals
