摘要：

A dc-11.5 GHz low-power amplifier is developed in commercial 0.13-mu m, CMOS technology. This amplifier design is based on a three-stage shunt-feedback inverter-configuration with splitting load inductive peaking technique. The peaking inductor is placed at the gate of the nMOS to compensate gain roll-off of the inverter stage and extend its operating bandwidth. This amplifier achieves a gain flatness of 13.2 +/- 1 dB from dc to 11.5 GHz with I/O return. losses better than -8/ -17 dB at a power consumption of 9.1 mW. The measured noise figure is less than 5.6 dB between 1-11 GHz. The output P1 dB is -8 dBm and input third-order intercept point is -10 dBm. The total chip size is 0.34 mm(2) including all testing pads, with a core area of only 0.08 mm(2).
