dc.description.abstract | A high-linearity and high-efficiency MMIC power amplifier is proposed that adopts a new on-chip adaptive bias control circuit, which simultaneously improves efficiency at the low output power level and linearity at the high output power level. The adaptive bias control circuit detects the input power level and supplies a low quiescent current of 16 mA at the low output power level and an increased current up to 90 mA according to the increased power level adaptively. The intelligent W-CDMA power amplifier using the adaptive bias circuit exhibits an improvement of average power usage efficiency of more than 1.93 times, and an adjacent channel leakage ratio by 4 dB at the output power of 28.3 dBm. | - |
