ADAPTIVE BIAS CIRCUIT AND POWER AMPLIFIER |
| 摘要 |
A bias circuit may include an envelope detecting unit detecting an envelope of an input signal, a source voltage generating unit generating a source voltage using a power supply voltage, and an envelope amplifying unit receiving the power supply voltage and the source voltage as a driving voltage and amplifying an envelope signal detected by the envelope detecting unit to generate a first bias voltage. |
