Abstract:
1. A method for single event transient filtering in an integrated circuit device, the device comprising first, second, and third sequential elements, each sequential element having a data input and a data output, and the device further comprising a first voting gate with first, second and third inputs, wherein the data output of the first sequential element is coupled to the first input of the first voting gate, the data output of the second sequential element is coupled to the second input of the first voting gate, and the data output of the third sequential element is coupled to the third input of the first voting gate, the method comprising the steps of: (a) generating first and second nominally equivalent logic signals in first and second SET domains; (b) converting the first and second nominally equivalent logic signals into first, second and third nominally equivalent data channels; and (c) transmitting the first, second and third nominally equivalent data channels to the data inputs of the first, second and third sequential elements respectively.
