Abstract
Fully-electronic detection of cells and microbeads is achieved on a 320x320 array of capacitive sensors in 0.35μm 2P3M CMOS technology that also integrates particle actuation by dielectrophoresis. Particle-associated equivalent input capacitance variations larger than 0.42fF are measured with 39dB SNR. Output noise is ≤1.6mV, the resolution of the 12b ADC.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
