Abstract
An apparatus includes a first amplifier, a second amplifier, and a compensation-setting generator to generate a first amplifier compensation setting and second amplifier compensation setting. A controller is operable to: i) apply the first amplifier compensation setting to the first amplifier and apply the second amplifier compensation setting to the second amplifier. The controller is further operable to switch between generating updates to the first amplifier compensation setting and the second amplifier compensation setting.
Claims32
An apparatus comprising:
- a first amplifier operable to receive a first signal;
- a second amplifier operable to receive a second signal;
- a compensation-setting generator operable to:
- i) receive the first signal inputted to the first amplifier, ii) derive a first differential compensation setting from the first signal, iii) receive the second signal inputted to the second amplifier, and iv) derive a second differential compensation setting from the second signal;
- and
- a controller operable to:
- i) apply the first differential compensation setting to the first amplifier and apply the second differential compensation setting to the second amplifier, and ii) switch between generating updates to the first differential compensation setting applied to the first amplifier and the second differential compensation setting applied to the second amplifier.
A method comprising:
- deriving a first differential compensation setting from a first signal inputted to a first amplifier;
- deriving a second differential compensation setting from a second signal inputted to a second amplifier;
- applying the first differential compensation setting to the first amplifier;
- applying the second differential compensation setting to the second amplifier;
- and
- switching between updating the first differential compensation setting applied to the first compensator and the second differential compensation setting applied to the second amplifier.
Computer-readable storage hardware having instructions stored thereon, the instructions, when carried out by computer processor hardware, cause the computer processor hardware to:
- derive a first differential compensation setting from a first signal inputted to a first amplifier;
- derive a secon differential compensation setting from a second signal inputted to a second amplifier;
- apply the first differential compensation setting to the first amplifier;
- apply the second differential compensation setting to the second amplifier;
- and
- switch between updating the first differential compensation setting applied to the first amplifier and updating the second differential compensation setting applied to the second amplifier.
