Abstract
Systems and methods are disclosed that employ a programmable analog-to-programmable digital converted system. A programmable analog-to-digital converter system comprises a quantizer assembly and configuration control. The quantizer assembly is configurable to provide at least one quantization stage. A given quantization stage converts an associated analog signal into an associated digital output signal. The configuration control selects among a plurality of configurations and configures the analog-to-digital converter system according to the selected configuration. The quantizer assembly is configurable to provide a plurality of quantization stages arranged in series in a first configuration, or to provide a single quantization stage in a second configuration.
Claims28
A programmable analog-to-digital converter (ADC) system comprising:
- a quantizer assembly, configurable to provide at least one quantization stage, a given quantization stage converting an associated analog signal into an associated digital output signal;
- and
- a configuration control that selects among a plurality of configurations and configures the ADC system according to the selected configuration, the quantizer assembly being configurable to provide a plurality of quantization stages arranged in series in a first configuration, and the quantizer assembly being configurable to provide a single quantization stage in a second configuration.
A programmable analog-to-digital converter (ADC) system, comprising means for selecting a configuration from a plurality of configurations associated with the programmable ADC;
- means for quantizing an analog input signal;
- and
- means for configuring the ADC system according to the selected configuration, the means for configuring including means for configuring the means for quantizing to provide two associated quantization stages arranged in series and means for configuring the means for quantizing to provide one associated quantization stage.
A method of configuring a programmable analog-to-digital converter (ADC) comprising:
- selecting between at least a first configuration and a second configuration, the first configuration being characterized in that a quantizer assembly associated with the programmable ADC is configured into a single quantization stage and the second configuration being characterized in that the quantizer assembly is configured into a plurality of quantization stages, with at least two of the plurality of quantization stages being configured in series;
- and
- configuring the quantizer assembly according to the selected configuration.
