Abstract: An N-path filter with one or more branches selectively coupled to a shared circuit node includes a first branch having a first feedback path and a second feedback path. The first feedback path includes a Miller amplifier having an input coupled to an input voltage and a first capacitor coupled to both the input voltage and an output of the Miller amplifier. The second feedback path includes a node in common with the first feedback path. The second feedback path also includes a first high pass filter coupled to the output of the Miller amplifier and a second capacitor coupled to both the first capacitor and the first high pass filter.

Abstract: The disclosure generally relates to a deoxyribonucleic acid (DNA) sequencing circuit having a controllable pore size and a lower membrane capacitance and noise floor relative to biological nanopore devices. For example, design principles used to fabricate a fin-shaped field effect transistor (FinFET) may be applied to form, on a first wafer, a nanopore that has a desired pore size in a silicon-based membrane. Electrodes and an interconnect embedded with an amplifier and analog-to-digital converter (ADC) may be formed on a separate second wafer, wherein the first wafer and the second wafer may then be bonded and further processed to form a sensing device that includes appropriate wells and pores to be used in a DNA sequencing circuit.

Abstract: This disclosure provides systems and apparatuses for converting a single-ended analog signal into a differential analog signal. In some implementations, a single-ended to differential signal converter may include an N-path filter to generate a 180 degree phase-shifted version of a single-ended input signal. The single-ended input signal and the 180 degree phase-shifted version of the single-ended input signal together may form a differential signal. In some implementations, the N-path filter may delay the single-ended input through a series of switched capacitors.

Abstract: An ionic current sensor array includes a master bias generator and a plurality of sensing cells. The master bias generator is configured to generate a bias voltage. Each sensing cell includes an ionic current sensor, an integrating capacitor, a sense transistor coupled between the integrating capacitor and the ionic current sensor, and an amplifier coupled to provide a reference voltage to bias the ionic current sensor. The amplifier includes a first transistor and a second transistor. The first transistor is coupled to receive the bias voltage, and the second transistor is coupled to the first transistor to provide the reference voltage to the ionic current sensor. The second transistor is also coupled between a source of the sense transistor and the gate of the sense transistor.

Abstract: Certain aspects of the present disclosure provide a local oscillator (LO) for wireless communication. In some examples, the LO is configured to generate an LO signal by inverting, by a first inverter, a first signal to generate a second signal having a first frequency, the first signal being an oscillating signal. In some examples, the LO is configured to control, using a third signal having a second frequency, a first switch receiving the second signal. In some examples, the LO is configured to control, using a fourth signal having the second frequency, a second switch receiving the second signal, wherein the fourth signal is a complement of the third signal and wherein the second frequency is one-half the first frequency.
