| Popis: |
A dual band (2G/5G) IEEE 802.11b/g/n/ac wide-band AM-AM envelope feedback power amplifier with digital pre-distortion is demonstrated in 40nm CMOS. This architect effectively improves both EVM and spectrum mask up to 20.9dBm in 40MHz bandwidth at 2G and 17.2dBm in 80MHz bandwidth in 5G. In addition, comparing to the conventional class AB PA, the power consumption is significantly reduced by 33% at low output power ( 16dBm). |
