The circuit includes several sub-circuits in which current signals are stored, at least one of the sub-circuits having a switch. The sub-circuits each include a voltage-controlled current source. The current sources have input capacitances that differ from each other by a factor of 10 or less, preferably by a factor of 5 or 2 or less. Each of the sub-circuits may have a switch, all switches lying at the same potential. The circuit may include output transistors which have widths which are different from that of an input transistor. The transistor widths may differ from each other by a factor of 10 or less.
