发明名称 Timing generator and test apparatus
摘要 A timing generator includes a reference clock generating unit for outputting a reference clock at a predetermined time interval, a first variable delay circuit unit for receiving the reference clock and outputting a first delay signal which results from delaying the reference clock, a second variable delay circuit unit for receiving the reference clock and outputting a second delay signal which results from delaying the reference clock, a delay control unit for controlling delay amounts of the first and second variable delay circuit units, and a timing generating unit for generating the timing signal based on the first and second delay signals, wherein the first and second delay control units increase or decrease the delay amounts of the first and second variable delay circuit units to be increased or decreased whenever the reference clock generating unit generates the reference clock.
