A method and circuit to perform noise shaped splitting of a digital input signal may include using multiple layers to process the input signal. In the first layer, the most significant bits of the input signal may be distributed to a plurality of branches. Dynamic element matching may be performed using the least significant bits of the input signal. Based on the results of the dynamic element matching, values may be added to the plurality of branches. If there is insufficient data activity, dynamics enhancement may be performed to increase the data activity. The output signals of each of the plurality of branches in the first layer may be provided to a second layer, in which these steps can be repeated on each of the output signals. The outputs of the second layer may be provided to a plurality of three level unit elements. |
