Amplifier circuit and integrated circuit therefor |
摘要 |
An amplifier circuit on a single die comprises a low voltage amplifier with a first common mode voltage and having an input and an output. A power amplifier has a second common mode voltage whose input is operably coupled to an output of the low voltage amplifier. The first common mode voltage and second common mode voltage are unequal. A compensation circuit is operably coupled to an input of the power amplifier and arranged to inject a DC-current or apply a common mode voltage into the power amplifier that is representative of a difference between the first common mode voltage and the second common mode voltage. |
