Design of a Flexible Analog Signal Conditioning Circuit for DSP-Based Systems

This paper presents the design of a flexible analog signal conditioning circuit (SCC) able to be reconfigured de- pending on user requirements. The SCC can be employed with DSP-based systems. The design is aimed to be used in power electronics applications where a wide range of signals types are present. In order to guarantee reconfiguration, the design is constituted of interconnected stages that can be activated depending on the characteristics of the input signal. The proposed circuit is a simple and a low cost solution because it employs off-the-shelf components.
