AUDIO AMPLIFYING CIRCUIT WITH IMPROVED NOISE PERFORMANCE |
摘要 |
An amplifying circuit includes a first circuit component configured to receive and amplify first and second input voltages to generate an output voltage. The first circuit component is formed by a first amplifier and a second amplifier. A second circuit component is configured to provide a first offset current that is associated with a first input current of the first amplifier. The first offset current compensates for variation in the first input current. A third circuit component is configured to provide a second offset current that is associated with a second input current of the second amplifier. The second offset current compensates for variation in the second input current. |
