    摘要： A circuit for measuring an unknown resistance of a resistive element comprises a sensor circuit to generate a differential voltage dependent on the resistance of the resistive element (VBE1, VBE2) and a reference circuit to generate a differential reference voltage (VBE3, VBE4) and a sigma-delta converter comprising a first stage (400), wherein a first capacitor (C2P) is selectively coupled to one of the output terminals of the sensor circuit and a second capacitor (C1P) is coupled to one of the output terminals of the reference circuit. The circuit generates logarithmically compressed values.

    摘要： Provided are switch deterioration detection device and method. More particularly, the switch deterioration detection device includes: a resistor serially connected with a battery in which charge and discharge are controlled through a switch; a first differential amplifier configured to amplify a voltage difference between both ends of the switch to output the amplified voltage difference as a first output voltage; a second differential amplifier configured to amplify a voltage difference between both ends of the resistor to output the amplified voltage difference as a second output voltage; a comparator configured to compare levels between the second and second output voltages; and a controller configured to determine whether the switch deteriorates based on the compared result of the comparator.
