Circuits for providing class-e power amplifiers

Abstract

In some embodiments, circuits for providing Class-E power amplifiers are provided, the circuits comprising: a first switch having a first side and a second side; a first Class-E load network coupled to the first side of the first switch; a second Class-E load network; and a second switch having a first side and a second side, the first side of the second switch being coupled the second side of the first switch and the second Class-E load network. In some embodiments, the circuits further comprise: a third switch having a first side and a second side; a third Class-E load network coupled to the first side of the third switch; a fourth Class-E load network; and a fourth switch having a first side and a second side, the first side of the fourth switch being coupled the second side of the third switch and the fourth Class-E load network.

What is claimed is: 
     
         1 . A circuit for forming an amplifier comprising:
 a first switch having a first side and a second side;   one of a first inductor and a first transmission line, the one of the first inductor and the transmission line having a first side connected to the first side of the first switch and having a second side connected to a non-ground power supply voltage;   one of a second inductor and a second transmission line, the one of the second inductor and the second transmission line having a first side and a second side, the second side of the one of the second inductor and the second transmission line connected to a non-ground power supply voltage; and   a second switch having a first side and a second side, the first side of the second switch being directly connected to the second side of the first switch and the first side of the one of the second inductor and the second transmission line.
