A Wide-Band Digital Lock-In Amplifier and Its Application in Microfluidic Impedance Measurement

In this work, we report on the design of a wide-band digital lock-in amplifier (DLIA) of up to 65 MHz and its application for electrical impedance measurements in microfluidic devices. The DLIA is comprised of several dedicated technologies. First, it features a fully differential analog circuit, wh...
