Abstract: A signal gate is provided where the gate can be low impedance to allow a signal to pass or be high impedance to block it. The signal gate has two output nodes arranged such that during the blocking mode spurious signals passing through the gate by way of parasitic components are presented as common mode signals at the output nodes.

Abstract: A method and a digital-to-analog converter (DAC) circuit involve forming an analog signal using charge sharing operations. The DAC circuit includes a plurality of digital components with associated parasitic capacitances. The digital components are activated based on a digital input code, such that charge is shared among the parasitic capacitances to form a first analog signal proportional to the digital input code. The digital components can also be activated based on a complementary code to form a second analog signal. The first analog signal and the second analog signal can be used to form, as a final output of the DAC circuit, an analog signal that is linearly proportional to the digital input code.

Abstract: Embodiments of the present disclosure relate to various methods and example systems for carrying out analog-to-digital conversion of data acquired by arrays of nanogap sensors. The nanogap sensors described herein may operate as molecular sensors to help identify chemical species through electrical measurements using at least a pair of electrodes separated by a nanogap. In general, the methods and systems proposed herein rely on digitizing the signal as the signal is being integrated, and then integrating the digitized results. With such methods, the higher sample rate used in the digitizer reduces the charge per quantization and, therefore, the size of sampling capacitors used. Consequently, sampling capacitors may be made factors of magnitude smaller, requiring less valuable space on a chip compared to sampling capacitors used in conventional nanogap sensor arrays.
