The Curve Tracer project aims to visualize the electrical characteristics of various electronic components and systems. It involves interconnecting simple and modular circuits to achieve the desired functionality. The device operates by varying the voltage across the Device Under Test (DUT) and measuring the current through it. The report discusses the basic concept, motivation, and design approach of the Curve Tracer.
The Curve Tracer system is divided into five subsystems: Astable multivibrator, Relaxation oscillator, Integrator, Ramp Generator, and Current mirror. Each subsystem plays a crucial role in generating and controlling the waveforms required for testing electronic components. The report provides detailed insights into the functionality and design considerations of each subsystem.
