Abstract
The present invention provides for adjusting the delay time interval of an input signal by controlling the internal register value and internal signal in a semiconductor integrated circuit device, or an external signal. The invention comprises a first gate arrayfor carrying out fine adjustment of the delay time interval of the input signal, capacitancestoandtoconnected to the output side of a specified gate in the first gate array via first switching devicetoa second gate arrayfor carrying out rough adjustment of the delay time interval of the input signal; and a control devicethat adjusts the delay time interval of the input signal by adjusting the capacitances connected to the output side of a specified gate in the first gate array and the number of gate stages in the second gate array
