  • Patent number: 11585784
    Abstract: Techniques described herein can apply AC signals with different phases to different groups of nanopore cells in a nanopore sensor chip. When a first group of nanopore cells is in a dark period and is not sampled or minimally sampled by an analog-to-digital converter (ADC) to capture useful data, a second group of nanopore cells is in a bright period during which output signals from the second group of nanopore cells are sampled by the analog-to-digital converter. The reference level setting of the ADC is dynamically changed based on the applied AC signals to fully utilize the dynamic range of the ADC.
