摘要:
A system includes an input shuffling circuit and digital-to-analog conversion circuitry. The input shuffling circuit includes a data input, a data output, and a control input. The input shuffling circuit is operable to receive, via the data input, an N-bit binary value, where N is an integer. The input shuffling circuit is operable to route each of the N bits of the N-bit binary word to one or more of M bits of the data output to generate an M-bit value, where M=2N, and the routing is based on a control value applied to the control input. The input shuffling circuit can be configured either in a dynamic element matching (DEM) mode or a regular binary to thermometer mode. The digital-to-analog conversion circuitry is operable to convert the M-bit value to a corresponding analog voltage and/or current. M different values of the control value may result in M different routings of the N bits of the binary word.
