Abstract :
A new concept for correcting errors in digital code is presented. For this purpose a programmable cellular nonlinear network can be used. To achieve high operation speed the high gain output nonlinearity is used. Positive range nonlinearity is combined to the high gain in order to achieve robust operation. The programmability of the network is reduced to only those coefficients actually needed in the processing to further increase the processing speed. An example of this coding scheme is given where the “bubbles” present at the thermometer code generated by a fast flash AID-converter are removed. For this correction operation simulations are given
