“…Some studies have used traditional measurement techniques such as the use of a vector network analyzer (VNA) [20] or a typical spectrum analyzer [21], a technique to characterize the AM/PM distortion for RF PAs and nonlinear devices [11,22], or the use of scalar power measurements of the PA [23]. More recently, in addition to calculating the PA's distortion curves [24,25], the works in [26][27][28] have used personal computers (PCs) as digital signal processors (DSPs) to reduce the cost of measurements. In this direction, and in order to provide a Contents lists available at ScienceDirect journal homepage: www.elsevier.com/locate/vlsi new low-cost alternative for obtaining PA distortion curves, a novel system based on FPGA is introduced herein.…”
