GLITCH-FREE ZERO-LATENCY AGC FOR SIGMA DELTA MODULATOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240022258 titled 'GLITCH-FREE ZERO-LATENCY AGC FOR SIGMA DELTA MODULATOR
Simplified Explanation
The abstract describes a patent application for a system that includes a sigma-delta modulator using a cascade-of-integrator feedback topology. The system performs operations such as applying a gain value to a group of feed-forward coefficients, determining a change in the gain value, and adjusting a plurality of state variables of the sigma-delta modulator during a clock cycle of a defined time period. The adjustment is done by multiplying each state variable by a scale factor that is a ratio of the gain value after determining the change in the gain value to the gain value before determining the change.
- The system includes a sigma-delta modulator with a cascade-of-integrator feedback topology.
- The system can apply a gain value to a group of feed-forward coefficients.
- The system can determine a change in the gain value.
- The system can adjust a plurality of state variables of the sigma-delta modulator during a clock cycle of a defined time period.
- The adjustment is done by multiplying each state variable by a scale factor that is a ratio of the gain value after determining the change to the gain value before determining the change.

Original Abstract Submitted
a system, comprising: a sigma-delta modulator using an integrator of a cascade-of-integrator feedback topology to perform operations is disclosed. the operations can comprise in response to receiving a gain value, applying the gain value to a group of feed-forward coefficients, determining a change in the gain value, and adjusting, during a clock cycle of a defined time period, a plurality of state variables of the sigma-delta modulator by multiplying each of the state variables by the scale factor that is a ratio of the gain value after determining the change in the gain value the gain value before determining the change in the gain value.
