- 应用说明英语AI 生成的摘要: Capacitive touch sensors measure capacitance changes caused by finger contact using a sensor drive pulse and current measurement. Ripple noise from the power supply or peripheral circuits distorts these measurements by adding noise currents, causing inaccurate touch detection. To ensure high accuracy and reliability, power supply design must minimize ripple noise. The document explains measurement principles, ripple noise effects, and countermeasures including power supply circuit selection, switching circuits, board layout, and touch parameter tuning. It covers RX, RL78, and RA family MCUs embedding CTSU1 and CTSU2 types of capacitive touch sensing units.
