Course Overview and Objectives

This is an advanced training course designed for engineers who design high-sensitivity analog circuits or sensor-based systems, systematically covering the operating principles of low-noise and low-power circuits, trade-offs, micro-current measurement techniques, constant current source design, and sensor interface structures.

Based on 35 years of practical experience by Professor Sung-Jae Cho from Shinhan University,

the course provides in-depth coverage of the key aspects of high-precision measurement circuit design: noise and sensitivity degradation issues in low-noise/low-power design, error factors in IV Converter operation in the pA~nA range, constant current source structures based on TR, OP AMP, and FET, practical considerations in ADC input voltage conversion design, and sensor interface configuration by sensor type.
