High impedance and compact neural sensor front-end
A front-end device is arranged to amplify an electric signal from an associated sensor, e.g. for amplifying an electric signal from a neural activity sensor. The front-end device has an amplifier circuit connected between its input and output terminals (Vin, Vout), wherein the amplifier circuit comprises a capacitive-coupled chopper circuit comprising a first gain element and first, second and third chopper switches arranged for operating at a chopper frequency. Further, the amplifier circuit has A) an impedance boosting auxiliary path connected to the input terminal in parallel with a first chopper switch of the CCC, wherein the impedance boosting auxiliary path comprises a pre-charging buffer, and B) a second gain element connected in a feedback path of the CCC. Such front-end device has high input impedance, and the input impedance is uncorrelated with the gain. It is highly suited for implantable micro devices, e.g. brain dusts.
