HIGH RESOLUTION PROGRAMMABLE PULSE GENERATOR |
摘要 |
A HIGH RESOLUTION PROGRAMMABLE PULSE GENERATOR A programmable pulse generator that uses high resolution programmable delay circuits (HRPDCs) as building blocks, each of which is capable of changing timing "on-the-fly", i.e., modifying the programmable delay within one tester cycle and without the limitations of existing delay circuits. The pulse generator comprises a timing control array that is subdivided into three components providing coarse delay, fine delay and extra-fine delay; a plurality of timing generators respectively controlled by the timing control array, each generator further comprising a plurality of HRPDCs, programmable delay circuits, and fixed delay blocks appropriately combined to modify pulse delay and pulse edges within each cycle.
