A 10 M \mathrm, 50 kHz-40 MHz Impedance Measurement Architecture for Source-Differential Flow Cytometry

A low-power, impedance-based integrated circuit (IC) readout architecture is presented for cell analysis and cytometry applications. A three-electrode layout and source-differential excitation cancels baseline current prior to the sensor front-end, which enables the use of a high-gain readout circui...
