METHOD OF USING INTEGRATED POWER AMPLIFIER |
摘要 |
An output-impedance in a power amplifier is provided. A first transistor QBUF of a buffer stage is connected to a first side of a resistor RF and a second transistor QAMP to a second opposite side of the resistor RF. The first transistor feeds a current IRF to the second resistor QAMP. The current IRF at the second transistor is copied and multiplied by a factor (n) to form an output current IOUT, as (1+n)* IRF. The current IRF is fed back to the first transistor and the output current IOUT is fed to a load resistor R.
