In depth characterization of nanopores such as ion channel proteins holds great value for medical and pharmaceutical applications. In this paper, an electrochemical interface circuit (EIC) is presented that enables both readout of individual nanopores and high throughput implementation within a lab-on-CMOS array platform. The EIC was designed for an electrochemical array microsystem that would facilitate...
This paper presents instrumentations for high throughput single ion channel recording array used for proteomics. The instrumentations incorporates two-stage amplifier using shared operational transconductance amplifier structure. The proposed sensor frontend reduces power consumption and area of circuit without any performance degradations in terms of bandwidth and noise. Two compact, low noise, low...
Based on Lyapunov stability theory, a holistic analysis approach is proposed for self-excited induction generator under no-load in the stationary reference frame with the transient mathematic model. Through analysis for initial transient states, a sufficient condition is fixed to be the limit cycle. The analytic formulas of the stator frequency, critical excitation capacitance and critical rotor speed...
The contactless conductivity has attained great attention in the last decade. But the application of contactless conductivity is restricted by its sensitivity, how to improve the sensitivity has become the key of contactless conductivity. Some simple equivalent circuits have been used to explain the basic functioning of a capacitively coupled contactless conductivity detector, it can not explain some...
