PURPOSE: A phase delay signal generator, equipment for a chip test including the same, and a method for creating a phase delay signal are provided to prevent the generation of mismatch and to eliminate PVT variation in a linear delay cell. CONSTITUTION: A phase delay signal generator comprises a digital control vibrator(100), a controller(200), a plurality of single phase generators(300), and a multiplexor(400). The digital control vibrator creates a reference signal. The controller controls the digital control vibrator. The plurality of single phase generators locks an input signal inputted from a fixed number delay generator to a reference signal created by the digital control vibrator and creates a plurality of single phase delay signals. The multiplexor selects a special signal among the plurality of single phase delay signals and transfers the special signal to a linear phase delay cell. |
