Abstract

A timing generator module is constructed from a single multitap active delay line circuit. The delay line taps are customized to delay an input pulse by different amounts, the differences between the amounts being selected as a function of the widths of the output pulses to be generated by the module. The output pulses from each of a number of different pairs of taps are logically combined within corresponding ones of a number of output logic gate circuits. A selected one of each pair of pulses is inverted before being logically combined with the other pulse of the pair for accurately controlling the transitions of the corresponding output pulse. The active delay line circuits are packaged within a single dual line package for maintaining accurate tolerances.
