Real number models for op amp filters implemented in VHDL
Adrian Virgil Craciun · 2017
This paper presents simulation models of filters with operational amplifiers that can be used in digital simulators. It describes the real number modeling used for analog functionally, presents a practical implementation of the most important analog “component” - the operational amplifier used in a 1storder low-pass filter, and compares the proposed filter models with the classical SPICE models of similar circuits.
