PURPOSE:To attain fine-adjustment of a delay time by connecting plural capacitors in parallel or in series via fuses. CONSTITUTION:The total capacitor capacitance being a combined capacitance of capacitors connected in series or in parallel is adjusted by selectively blowing out 1st stage fuses F111, F112,...F11m, F11(m+1),...F11n, 2nd stage fuses F141, F142,...F14m, F14(m+1),...F14n, and 3rd stage fuses F131, F132,...F13m, F13(m+1),...F13n so as to change number of capacitors or connection form connected electrically to a signal line 13. Since lots of total capacitance values are set over a wide range, fine-adjustment of the delay time is easily implemented. |
