Abstract

This paper presents a streamlined design flow for an integrated power amplifier. For a given set of amplifier specifications and BiCMOS process parameters, a software routine computes passive component values for a Class-E or Class-F based power amplifier. The routine includes a matching network for standard impedance loads. Spiral inductor search algorithm is used to generate inductors with Q-factors optimised at a desired frequency. Operation of the software routine is demonstrated by simulations in Austriamicrosystems 0.35 µm single-supply process for the 10 dBm, 2.4 GHz power amplifier design.
