Abstract
A data-hold timing adjustment circuit having resistance wires to which a power-supply voltage is supplied, formed along numerous flip-flops. MOS variable capacitors 3i and 4i (i=1 to n) are connected at one electrode to the data input end of the flip-flops and at another electrode to the resistance wires. The composite capacitance of the MOS capacitors becomes larger as the value of i increases, independent of the voltage level of the data input end of the flip-flops. When the potential of the data input end of the flip-flop shifts from a high/low level to a low/high level, this shift is delayed more as the value of i becomes larger, while the clock input to the flip-flop is delayed more as the value of i becomes larger.
