Electronic Circuit for Adjusting an Offset of a Differential Amplifier |
摘要 |
An electronic circuit has a differential amplifier with a differential transistor pair having two transistors. The electronic circuit also has two digital-to-analog converters, a respective one of the two digital-to-analog converters coupled to each respective one of the two transistors. Control bits adjust the DACs to provide an offset voltage adjustment of the differential amplifier. |
