N2 - An ASIC for ambulatory EEG systems includes eight readout channels, an 11 b ADC, a clock oscillator and a calibration signal generator, and has an electrode impedance measurement mode. The chopped instrumentation amplifier (IA) of the readout channel has 120dB CMRR, 1 GΩ input impedance and 0.57μVrms total noise in a 0.5 to 100Hz BW, while drawing 2.3μA from a 3V supply. The noise efficiency factor of the chopped IA is 4.1.
