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.
Claims8
A buffer circuit comprising:
- a current mode circuit configured to generate an output signal based on a power voltage and an input signal and configured to compensate for a transition timing change of the output signal based on a level of a bias voltage;
- and
- a bias generation circuit configured to generate the bias voltage based on a reference voltage, configured to detect a level change of the power voltage, and configured to control the level of the bias voltage based on detection results.
