Abstract
An electronic driving circuit for a microfluidic device, having a number of synchronized driving stages to generate a respective driving signal for each electrode or group of electrodes of the microfluidic device, the driving signals having a desired amplitude, frequency and phase-shift. Each driving stage has a switching-mode amplifier stage to receive a clock signal and a target signal and to generate, at an output thereof, an output signal defining a respective driving signal. The amplifier stage has: a switching module, coupled to a first internal node and controlled by the clock signal for selectively bringing the first internal node to a control signal; a filter module, coupled between the first internal node and the output, to provide the output signal; and a feedback module.
