Resumen:
The design of analog signal conditioning circuits for instrumentation applications often requires designing a specific circuit for each case. For board-level design solutions, these circuits are generally implemented by using Operational Amplifiers (OA) and Instrumentation Amplifiers (IA). An analog building block (ABB) is proposed, which can be implemented with three standard OAs. Using different connection schemes and just adding a few resistors, it allows implementing several analog circuits such as common-mode conditioners, single-ended to differential and differential to single-ended converters, voltage and current amplifiers, current-to-voltage and voltage-to-current converters, among others. The proposed ABB is analyzed and applied to several typical analog conditioning problems. The design equations and experimental results for these circuits are presented.
