A current-readout front-end for nanosensors based on a ΔΣ converter approach features an input-equivalent noise of 5fA/√Hz in a 1kHz bandwidth.The front-end detects ion-channel activity caused by single-molecule interactions. The device occupies 0.5mm2 in 0.35μm 2P4M CMOS and consumes less than 23mW.

Abstract
A current-readout front-end for nanosensors based on a ΔΣ converter approach features an input-equivalent noise of 5fA/√Hz in a 1kHz bandwidth.The front-end detects ion-channel activity caused by single-molecule interactions. The device occupies 0.5mm2 in 0.35μm 2P4M CMOS and consumes less than 23mW.File in questo prodotto:
