ABSTRACT:
An integrated delay circuit has been provided which comprises a bipolar transistor and more particularly a PNP transistor having a diffusion capacitor of a given storage capacity as a time delay element and means including a switching device coupled to the junction capacitor for controlling current flow through the transistor. The switching device, which is preferably a Schottky diode, includes a capacitor having a charge storage capacity less than, and preferably substantially less than, that of the transistor. In the closed condition of the switching device a constant or steady current is sustained through the transistor and in the opened condition of the switching device the current through the transistor decreases exponentially. By coupling the output current from the transistor to a current level detector or comparator controlled delay times of substantial duration are produced in bipolar circuit technology.
