    摘要: A capacitor array circuit receives a plurality of input signals, generate a single output signal by combining the plurality of input signals, and output the single output signal. A comparator receives the output signal of the capacitor array circuit. A current source, which is disposed between a predetermined fixed voltage source and an output terminal of the switched-capacitor circuit, supplies the current to the output terminal until the output signal of the comparator changes. A plurality of input capacitors in the capacitor array circuit receives a plurality of input signals in parallel with each other. At least one additional regulating capacitor in the capacitor array circuit store the charge to compensate for an offset component caused by the delay in the comparator. The respective output terminals of the plurality of input capacitors and the at least one additional regulating capacitor are combined into one.

    摘要: The present invention quickly detects an offset and prevents cutoff of low frequency signals. Offset detection circuits smooth an output of a variable gain amplifier at a predetermined time constant and detects the offset, which is a DC component. The detected offset is added to the input of the variable gain amplifier by an adder and the offset in the output of the variable gain amplifier is corrected. The time constant in the offset detection circuit is changed by the resistance values of the variable resistors. Then, the time constant is changed to a small time constant when the gain of the variable gain amplifier is changed and thereafter to a large time constant.
