CHARGE PUMP BASED POWER AMPLIFIER ENVELOPE POWER SUPPLY AND BIAS POWER SUPPLY |
摘要 |
The present disclosure relates to a direct current (DC)-DC converter, which includes a charge pump based radio frequency (RF) power amplifier (PA) envelope power supply and a charge pump based PA bias power supply. The DC-DC converter is coupled between RF PA circuitry and a DC power supply, such as a battery. As such, the PA envelope power supply provides an envelope power supply signal to the RF PA circuitry and the PA bias power supply provides a bias power supply signal to the RF PA circuitry. Both the PA envelope power supply and the PA bias power supply receive power via a DC power supply signal from the DC power supply. The PA envelope power supply includes a charge pump buck converter and the PA bias power supply includes a charge pump. |
