Abstract
The discrete time analog circuit () is provided with: a rotate capacitor circuit (); an amplifier () that is connected to the input line or the output line of the rotate capacitor (), and amplifies the input potential or input charge; a coefficient circuit () that is positioned in series with the amplifier (), and has two history capacitors (--) positioned parallel to each other; a first active capacitor among the two history capacitors (--) that is connected to and charges the amplifier (); and a clock generation circuit () that is connected to the input line or the output line without the involvement of the amplifier (), and that sequentially changes the pairing of the rotate capacitor circuit () a second active capacitor, which shares a charge with the rotate capacitor circuit ().
