Abstract
A bias generation circuit may include a bias generator and compensator. The bias generator may be configured to generate a bias voltage based on a reference voltage. The compensator may be configured to detect level changes of a power voltage. The compensator may be configured to control a level of the bias voltage based on detection results.
Claims5
A bias generation circuit comprising:
- a bias generator configured to generate a bias voltage based on a reference voltage;
- and
- a compensator configured to detect level changes of a power voltage and configured to control a level of the bias voltage based on detection results,
- wherein the compensator comprises:
- a voltage change tracker configured to detect the change of the power voltage;
- a low pass filter configured to remove a high-frequency component from an output of the voltage change tracker to allow a low-frequency component to pass through the low pass filter;
- and
- a bias level controller configured to control the level of the bias voltage based on an output of the low pass filter.
