The principle of an automatic VHDL code generator dedicated to the control of the electric systems is presented in this paper. From the definition of classic regulator, it is possible to envisage a direct integration of the digital regulator in a FPGA component. The advantage of using a FPGA rather than a micro-controller lies in the fact of reaching very high sampling frequencies, allowing to obtain...
This paper examines a practical method to reduce the spectral distortion at the output of an envelope elimination and restoration (EER) power amplifier (PA). The EER amplifiers utilized in terrestrial amplitude modulation (AM) radio broadcast transmitters are affected by non-linear and memory effects; the proposed compensation method exploits the source of these effects in real-world amplifiers. Specifically,...
