AMPLIFIER CIRCUIT, BIASING BLOCK WITH OUTPUT GAIN COMPENSATION THEREOF, AND ELECTRONIC APPARATUS |
| 摘要 |
An exemplary embodiment of the present disclosure illustrates an amplifier circuit comprising an amplifier block and a biasing block. The amplifier block is used to receive an input signal and amplify the input signal to generate an output signal. The a biasing block coupled to the amplifier block is used to provide biasing voltages to bias the amplifier block, and compensate an output gain of the amplifier block before the output gain of the amplifier block is compressed, so as to extend a P1 dB compression point of the amplifier block, wherein the biasing currents are substantially independent to temperature and/or system voltage variation. |

1. An amplifier circuit, comprising:
an amplifier block, used to receive an input signal, and amplify the input signal to generate an output signal; and a biasing block, coupled to the amplifier block, used to provide biasing voltages to bias the amplifier block, and compensate an output gain of the amplifier block before the output gain of the amplifier block is compressed, so as to extend a P1 dB compression point of the amplifier block, wherein the biasing current are substantially independent to temperature and/or system voltage variation. |
