This paper expounds a three-way Doherty power amplifier (3W-DPA) as a solution to the need for high-efficiency wideband power amplifiers when driven by multi-standard signals. The paper begins with a theoretical analysis of 3W-DPA architecture from w

Based on the analysis introduced in Chap. 4 about important dithering parameters, the most important ones are the slope gain and the parasitic capacitances of the device. The former maintains the dithered gain high enough for efficient and high gain

The preceding chapters were devoted to analysis and simulation of the dithering process, its linearization effect, and formulation of the in and out of band nonlinearities. According to the theoretical findings, dithering can linearize the system, an

The open loop and closed loop class-D amplifiers both opt for low frequency dithering for linearization, due to their high slope gain. They may opt for drain efficiency improvement, depending on their process technology, or intrinsic capacitance valu

Dithering is applicable to any nonlinear system, to enhance linearity. We normally use the dithering to linearize the switched mode power amplifiers, while benefiting from good efficiency. The system architectures can be in many different forms: open
