A novel bias circuit providing a stable quiescent current for temperature and supply voltage variations is proposed and implemented to a W-CDMA MMIC power amplifier. The power amplifier with the proposed bias circuit has the quiescent current variation of only 6% for the -30℃ to 90℃ temperature change, and 8.5% for the 2.9V to 3.1V supply voltage change, and the variation of the power gain at the 28dBm output power is less than±0.8(0.05)dB for the ±0.1V of supply voltage (±60℃ of temperature) variation.
