Abstract
An apparatus may include a scrambler element configured to receive an input signal and generate a scrambled thermometer code-like signal having a plurality of bits based on the input signal and having a plurality of possible quantization values. The scrambler element may generate at least one equivalent code of the scrambled thermometer code-like signal for each possible quantization value. For each of one or more of the possible quantization values, the scrambler element may be configured to generate a plurality of possible equivalent codes of the scrambled thermometer code-like signal. Responsive to the input signal indicating a change in quantization value of the scrambled thermometer code-like signal, the scrambler element may change the scrambled thermometer code-like signal by transitioning the smallest possible number of the plurality of bits of the scrambled thermometer code-like signal to change quantization value of the scrambled thermometer code-like signal in accordance with the input signal.
