Abstract

Examples of systems and methods are provided for generating an output signal having an output code having less number of bits compared to an input signal having a thermometer code representation. The system may partition the input code bits into non-overlapping clusters. The system may generate a control signal for each of the clusters based on, at least in part, a logical OR operation over all bits in a corresponding one of the clusters. The system may determine a transition cluster comprising a 1/0 transition in the input code bits. The system may determine output code bits based on, at least in part, an input code bit pattern in the transition cluster and an identity of the transition cluster.
