ABSTRACT:
A voting scheme for analog signals is described. An analog block is replicated to provide three analog blocks that are designed to have substantially the same analog output based on receiving substantially the same input. Voting is used to compare the analog outputs from the three analog blocks. In one example, the analog output from one of the three analog blocks having a middle value between the values of the other two analog outputs is provided as an output of the voter circuit. In another example, if the original analog block provides the analog output having the middle value, the output of the original analog block is provided as an output of the voter circuit. Otherwise, an output of another analog block is provided as an output of the voter circuit. In another example, the analog voter circuit determines which of the three analog outputs have been impacted by a transient event based on a non-zero output of transconductor circuits. These analog voting schemes may be incorporated into any circuit design in which an analog signal may be susceptible to SEE.
