Abstract: A two-capacitor digital-to-analog converter circuit having circuitry to compensate for an unwanted capacitance is disclosed. The converter is configured to generate an average voltage on two capacitors for a sequence of bits in a digital word so that when the final bit is reached, the average voltage corresponds to an analog level of the digital word. The converter is configured to input and average the voltage on the two capacitors using different modes to minimize the effects of capacitor mismatch and switching capacitance on the accuracy of the conversion. The converter includes a buffer amp that has an input capacitance that can affect the conversion. Accordingly, the converter further includes capacitance compensation circuitry configured to provide a replica input capacitance that can be charged and discharged according to the bits of the digital word and coupled to the input capacitor to prevent the input capacitance from affecting the conversion.

Abstract: A crystal oscillator circuit that can be controlled for fast start-up and for efficient operation is disclosed. The control includes adjusting a voltage applied to a body terminal of a transistor in order to control the amplification of the crystal oscillator. The amplification can be increased, relative to a motional resistance of the crystal oscillator, at start-up to reduce a start-up time necessary for oscillation. The amplification can also be decreased in order to maintain oscillation after start-up more efficiently. In some implementations, the transistor for control is a fully depleted silicon on insulator (FDSOI) transistor that accommodates a wide range of body bias voltages.

Abstract: Systems and methods include a system for processing health information for multiphase flow meters (MPFMs) of different types and at one or more different locations. Multiphase flow meter (MPFM) readings of different MPFM types are received in real-time from MPFMs at different locations. For each MPFM, an MPFM health rule that corresponds to the MPFM readings is determined using the MPFM readings and logic of MPFM health rules. A recommendation is determined for each MPFM based on the MPFM health rule. A health status and an alarm priority are determined for each MPFM using the MPFM readings and the logic of MPFM health rules. A dashboard is presented to a user that includes, for each MPFM, the MPFM readings, the recommendation, the health status, and the alarm priority.
