Generating Programmable Analog Signals using FPGA
Cristian Zet, Cristian Foşalău · 2019 International Conference on Electromechanical and Energy Systems (SIELMEN) · 2019
The present paper presents the possibilities of using FPGAs to generate analog signals and it makes an estimation of the accuracy of the output. Two ways of generating analog signals are analyzed: PWM (pulse width modulation) with passive analog filter and R2R resistive network. Besides the digital circuits, the accuracy of signals and the limitations are analyzed.
