Methods and systems are provided for spreading spectral density of pulse streams during digital to analog conversion. An example system may comprise an accumulator circuit, a bit generator circuit, and a feedback circuit. The accumulator circuit may be operable to receive a signal to be spread and generate an output based on the signal to be spread and on one or more inputs generated within the system. The bit generator circuit may be operable to input into the accumulator circuit sequences meeting at least one particular criterion. The feedback circuit may be operable to apply an adjustment to a signal corresponding to an output of the accumulator circuit to generate a feedback signal, and input the feedback signal into the accumulator circuit.

Methods and systems are provided for spreading spectral density of pulse streams during digital to analog conversion. An example spreading circuit may comprise an accumulator circuit, a bit generator circuit, a comparator circuit, and an inverter circuit. The accumulator circuit may be operable to receive a signal to be spread and generate an output based on the signal to be spread and at least one other input. The bit generator circuit may be operable to input into the accumulator circuit zero-sum sequences. The comparator circuit may be operable to provide a stream of pulses based on the output of the accumulator circuit. The inverter circuit may be operable to invert output of the comparator circuit, wherein output of the inverter circuit is input into the accumulator circuit.
