Abstract
Methods and apparatus for calibrating a gain for a circuit block are disclosed. An example method includes receiving a plurality of quantizer offsets, where the plurality of quantizer offsets represent calibration data for a quantizer configured to quantize an output of the circuit block, determining one or more differences based on one or more first quantizer offsets of the plurality of quantizer offsets and on one or more second quantizer offsets of the plurality of quantizer offsets, and determining an incremental change in a gain associated with the circuit block based on the one or more differences.

A method for calibrating a gain for a circuit block, comprising:
- receiving a plurality of quantizer offsets, the plurality of quantizer offsets representing calibration data for a quantizer configured to quantize an output of the circuit block;
- determining one or more differences based on one or more first quantizer offsets of the plurality of quantizer offsets and on one or more second quantizer offsets of the plurality of quantizer offsets;
- determining an incremental change in the gain based at least in part on the one or more differences.
A gain calibration apparatus for a circuit block, comprising:
- a first plurality of terminals to receive a plurality of quantizer offsets, the plurality of quantizer offsets representing calibration data for a quantizer configured to quantize an output of the circuit block;
- difference calculation logic configured to determine one or more differences based on one or more first quantizer offsets of the plurality of quantizer offsets and on one or more second quantizer offsets of the plurality of quantizer offsets;
- and
- gain calibration logic configured to determine an incremental change in a gain of the circuit block based at least in part on the one or more differences.
A non-transitory computer readable storage medium storing instructions that, when executed by one or more processors of a gain calibration apparatus, cause the gain calibration apparatus to perform operations comprising:
- receiving a plurality of quantizer offsets, the plurality of quantizer offsets representing calibration data for a quantizer configured to quantize a circuit block output;
- determining one or more differences based on one or more first quantizer offsets of the plurality of quantizer offsets and on one or more second quantizer offsets of the plurality of quantizer offsets;
- determining an incremental change in a gain of the circuit block based at least in part on the one or more differences.
