Stationary electro-osmotic flow driven by AC fields around charged dielectric spheres
(Cambridge University Press, 2021)
We experimentally demonstrate quadrupolar electro-osmotic flows around charged dielectric microspheres immersed in an electrolyte when subjected to an alternating current electric field. We present an electrokinetic model ...

A 12-Bit Low-Input Capacitance SAR ADC With a Rail-to-Rail Comparator
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2023)
The input capacitance of the SAR ADC is considered a drawback in many applications. In this paper, a 12-bit low-power SAR ADC with low-input capacitance is proposed. The ADC is based on a separated DAC and sample-and-hold ...
