Multi-zone data converters

摘要

Aspects of a method and system for data converters having a transfer function with multiple operating zones. In some embodiments, an operating zone of the multiple operating zones is characterized by more stringent performance criteria than the other operating zones. Thus, such data converters may receive an input signal and generate an output signal from the input signal per the transfer function and the more stringent performance criteria in the appropriate operating zone.

主权项

1. A method, comprising:
receiving a first input signal with a data converter having a plurality of operating zones; in response to determining that the first input signal corresponds to a first operating zone of the plurality of operating zones, converting the first input signal to a first output signal per a first circuit of the data converter; receiving a second input signal with the data converter; and in response to determining that the second input signal corresponds to a second operating zone of the plurality of operating zones, converting the second input signal to a second output signal per a second circuit of the data converter that has better operating characteristics than those of the first circuit.
