Abstract:
A single event effect immune oscillator circuit, comprising:a plurality of latch circuit blocks i connected in series, wherein each of said plurality of latch circuit blocks i has a first input, a second input, and an output, wherein each of said plurality of latch circuit blocks changes from one state to another state only when input signals of identical polarity are contemporaneously received by both said first input and said second input, wherein each of said latch circuit blocks i includes a dual-input inverter and a storage cell, wherein i=1 to n, wherein n is an odd number; and an output of a latch circuit block i is connected to a first input of a latch circuit block i+1 and to a first input of a latch circuit block i+x, wherein x is an odd number higher than one and less than or equal to n.
