  • 基于开关电容技术的锁定放大器设计

    锁定放大是微弱信号检测的重要手段。基于相关检测理论,利用开关电容的开关实现锁定放大器中乘法器的功能,提出开关电容和积分器相结合以实现相关检测的方法,并设计出一种锁定放大器。该锁定放大器将微弱信号转化为与之相关的方波,通过后续电路得到正比于被测信号的直流电平,为后续采集处理提供方便。测量数据表明锁定放 ...

  • DUAL DIGITAL ISOLATORS

    The ISO7220 and ISO7221 are dual-channel digital isolators. To facilitate PCB layout, the channels are orientedin the same direction in the ISO7220 and in opposite directions in the ISO7221. These devices have a logic inputand output buffer separated by TI’s silicon-dioxide (SiO2) isolation barrier ...
