微弱信号检测装置 四川理工学院 刘鹏飞、梁天德、曾学明 摘要： 本设计以TI的Launch Pad为核心板，采用锁相放大技术设计并制作了一套微弱信号检测装置，用以检测在强噪声背景下已知频率微弱正弦波信号的幅度值，并在液晶屏上数字显示出所测信号相应的幅度值。实验结果显示其抗干扰能力强，测量精度高。 关键词： ...

Abstract: Many industrial/scientific/medical (ISM) band radio frequency (RF) products use crystal oscillators to generate areference for the phase-locked loop (PLL)-based local oscillator (LO). This tutorial provides a basic description of theISM-RF Crystal Calculator, which can be used to calcula ...

Recently a new technology for high voltage Power MOSFETshas been introduced – the CoolMOS™ . Based on thenew device concept of charge compensation the RDS(on) areaproduct for e.g. 600V transistors has been reduced by afactor of 5. The devices show no bipolar current contributionlike th ...

This paper presents a space vector modulation(SVM)-based switching strategy for a three-level neutral point clamped (NPC) converter that is adapted as a STATCOM.
