摘要： A differential amplifier circuit is provided with an operational amplifier and a modulator. The operational amplifier includes a feedback capacitance, and amplifies an analog input signal and outputs an amplified analog output signal. The modulator is connected to a virtual ground point of an input terminal of the operational amplifier, and the modulator switches between a pair of inputted analog differential signals to alternately select one of the analog differential signals based on a predetermined modulation control signal, and outputs a selected analog differential signal. The differential amplifier circuit alternately folds and amplifies the analog input signal within a predetermined input level limit range to generate a signal having different polarities sequentially so as to start from a voltage potential of the virtual ground point at a timing of the modulation control signal. In addition, an converter apparatus is provided with the differential amplifier circuit.

摘要： In a feedback amplifier circuit, a first switching device executes an auto-zero operation by inputting a signal outputted from an amplifier to an input terminal of the amplifier during an auto-zero operation interval prior to an amplification interval. A first capacitor accumulates and holds an offset voltage at the output terminal of the amplifier during the auto-zero operation interval, and cancels an offset voltage at the input terminal of the amplifier by an accumulated and held offset voltage during an amplification interval subsequent to the auto-zero operation interval. A second switching device grounds the feedback point of the feedback circuit during the auto-zero operation interval. A second capacitor blocks a DC voltage, and accumulates and holds an offset voltage at an output terminal of the amplifier, and cancels an offset voltage at an input terminal of the amplifier by the accumulated and held offset voltage during an amplification interval.

摘要： In a sampling and holding, a control logic circuit connects another end of each capacitor of a DA converter to a ground potential, and outputs a sampled input analog signal from a switched amplifier to one end of a hold capacitor to hold. In a successive approximation, it controls a switched amplifier to set an output terminal thereof to a high-impedance state and the hold capacitor to connect the one end thereof to the ground potential. Then, it switches over connection of another end of each capacitor from the ground potential to a power supply voltage based on a digital value held by a successive approximation register to output an output voltage from another end of the hold capacitor to a comparator, and compares the output voltage from another end thereof with an intermediate reference voltage to obtain a digital value from the successive approximation register.
