• 光电二极管检测 荧光峰衰减问题

    图1: 图2: 图3:

    问题:图2是模拟出的现象,就是当给予光照信号时前面的几个光照信号峰存在衰减,甚至丢失荧光峰。

    已知信息:

    1.光照信号脉宽20ms左右。

    2.AD8605输出端经过导电滑环,接入图3CONN_AD1+端。

    3.图3AD_OUT1+端直接接AD7779进行模数转换。

    希望得到的帮助:

    1.帮忙分析产生荧光信号峰衰减的可能原因。

    2.现在的电路参数设计是否合理。

  • aperture jitter

    Hello everyone, a short question about LTC2378-20 ADC.

    At page 3 of the datasheet:

    https://www.analog.com/media/en/technical-documentation/data-sheets/237820fb.pdf

    there is the aperture jitter. Is that an RMS value or peak to peak?
