    摘要: A method of analyzing a molecule in a nanopore is disclosed. A voltage is applied across a nanopore that is inserted in a membrane by coupling the nanopore to a voltage source. The nanopore is decoupled from the voltage source. After the decoupling, a rate of decay of the voltage across the nanopore is determined. A molecule in the nanopore is distinguished from other possible molecules based on the determined rate of decay of the voltage across the nanopore.

    摘要: A nanopore measurement circuit includes a first analog memory configured to store a first electrical value corresponding to a first measurement sample of a nanopore and a second analog memory configured to store a second electrical value corresponding to a second measurement sample of the nanopore. The nanopore measurement circuit also includes a measurement circuitry configured to provide an output indicating a difference between the first electrical value of the first analog memory and the second electrical value of the second analog memory.

    摘要: A method of analyzing a molecule is disclosed. A voltage source is selectively connected to or disconnected from a capacitor using a switch controlled by a reset signal. A charge is stored in a capacitor when the voltage source is connected to the capacitor. The capacitor is discharged through a nanopore in a membrane when the voltage source is disconnected from the capacitor. A duty cycle of the reset signal is determined such that the voltage source and the capacitor is connected for at least a one tenth portion of a reset signal period and disconnected for a remaining portion of the reset signal period, such that a voltage across the nanopore is maintained at a higher level during the portion of the reset signal period in which the connection is maintained than during the remaining portion of the reset signal period in which the connection is not maintained.
