摘要： An accurate, cost-efficient temperature sensor may be integrated into an integrated circuit (IC) using common materials as the IC's interconnect metallization. The temperature sensor may include an impedance element having a length of metal made of the interconnect metal, a current source connected between a first set of contacts at opposite ends of the impedance element, and an analog-to-digital converter connected between a second set of contacts at opposite ends of the impedance element. The temperature sensor may exploits the proportional relationship between the metal's resistance and temperature to measure ambient temperature. Alternatively, such a temperature sensor may be used on disposable chemical sensors where the impedance element is made of a common metal as conductors that connect a sensor reactant to sensor contacts. In either case, because the impedance element is formed of a common metal as other interconnect, it is expected to incur low manufacturing costs.

摘要： An amplifier system can include a feedback amplifier circuit having an amplifier, a feedback capacitor connected between an input terminal and an output terminal of the amplifier by at least one first switch, and a reset capacitor connected across the feedback capacitor by at least one second switch and between a pair of reference voltages by at least one third switch. During an input-signal processing phase of operation, a control circuit may close the at least one first switch and open the at least one second switch to electrically connect the feedback capacitor between the input and output terminals to engage feedback processing by the feedback amplifier circuit, and close the third switch to electrically connect the reset capacitor between the first and second voltages to charge the reset capacitor to a selectable voltage difference. During a reset phase of operation, the control circuit may open the at least one third switch, close the at least one second switch and open the at least one first switch to electrically connect the reset capacitor across the feedback capacitor to reset the feedback capacitor using the reset capacitor. The amplifier system can optionally include a plurality of the feedback amplifier circuits.

摘要： The invention provides a systematic error correction network coupled to a converter. The converter may display a systematic non-linearity error, and the systematic error correction network shapes a correction transform function that acts like counter distortion function for the non-linearity error. The systematic error correction network then scales the correction transform function according to a reference variable, where the magnitude of non-linearity error is related to the reference variable. The scaled correction transform function is then applied to the converter path in order to generate a corrected analog output signal.

摘要： A circuit system for performing correlated double sampling may include a signal sampling stage having an amplifier with a feedback capacitor and a pair of storage capacitors coupled to an output of the amplifier, and a differential analog to digital converter (ADC) having a pair of inputs coupled respectively to storage capacitors of the signal sampling stage. The signal sampling stage may receive reset and signal values from a sensor device and may store processed versions of those signals on respective storage capacitors. The differential ADC may generate a digital value representing a signal captured by the sensor device from a differential digitization operation performed on the processed versions of the reset and signal values. In this manner, the system may correct for any signal errors introduced by components of the sampling stage.

摘要： A detector circuit can include an integrator having an amplifier, a first feedback capacitor connected between an input and output of the amplifier, one or more additional feedback capacitors connected by at least one switch between the input and output of the amplifier, and a shunt capacitor connected to the output of the amplifier. The shunt capacitor can be selected to have a capacitance value greater than that of a minimum but less than that of a maximum feedback capacitance. The detector circuit can further include a sampling circuit having a sampling capacitor connected to the output of the integrator amplifier through at least one switch, wherein the sampling capacitor is separate from the shunt capacitor. A computed tomography imaging apparatus can include the detector circuit.
