Abstract :
A CMOS radio-frequency power amplifier including on-chip matching networks has been designed in a 0.6-μm n-well triple-metal digital CMOS process, and optimized using a simulated-annealing-based custom computer-aided design tool. A compact inductor model enables the incorporation of parasitics as an integral part of the parasitic-aware design and CAD optimization; low-Q metal3 spiral inductors are used in the input and output matching networks. A 3-V 85-mW balanced fully integrated Class-C power amplifier with a measured drain efficiency of 55% at 900 MHz has been designed, optimized, integrated, and tested
