Analog circuits are sensitive to signal aggressions and power supply noise, crosstalk coupling and alpha particle strikes can cause significant degradation of circuit's SNR. This research proposes a novel approach to real-time transient error and induced noise cancellation in linear analog circuits using analog checksums. It is based on the use of state space representations of analog filters and...
Analog checksum based fault tolerance for linear circuits has been proposed in the past but remains a theoretical artifact due to the high cost and complexity of error compensation while other redundancy based methods have prohibitive overheads. To resolve this, new low cost error compensation methods for widely used linear analog circuits are developed in this research. Trial and error based compensation...
