A design tool, which exploits a State Space model description for the automatic design of a Class-E Power Amplifier, is here proposed.

Abstract
A design tool, which exploits a State Space model description for the automatic design of a Class-E Power Amplifier, is here proposed. The tool provides an automatic optimization of the filter components, just by inserting the design specifications and the starting values. The second step of the automatic iterative tuning allows preserving the highest value of power efficiency. All specifications realize a 3D matrix, which is able to converge (with 60 iterations in about 3s) to an optimal solution by using the crosscheck of the specifications. Finally, as case study, a η-optimal design has been implemented by using the proposed tool. We compare the analytical design of the Class E PA implemented in TSMC 65nm CMOS technology, with the State Space Model technique here described. The new design reaches an efficiency of 87% in simulation, with an η increment of 12% respect the original design.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
