2 OUTLINE Project motivation Design overview Body-Electrode Interface Voltage references Chopper Stabilized LNA Low Pass filter ADC Driver SAR-ADC Conclusion
3 PROJECT MOTIVATION Epilepsy neurological disorder Abnormal firing in a group of neurons Clinical onset: Loss of coherence/cognition Loss of motor control Convulsions Objective: sense these signals and establish correlation with clinical onset Use of machine learning techniques and training to patient-specific data
4 DESIGN OVERVIEW Multi Channel EEG Acquisition system Wireless low power chip Digitized EEG signals transmitted for processing Machine learning algorithm for processing channel signals IC design specifications
5 BODY-ELECTRODE INTERFACE Dry-electrode model: Gel free solution Increased impedance in the skin-electrode interface Circuit model: Resistor : body Resistor & Capacitance: Stratum Corneum Electrode offset voltage (EOV): mV EEG Signals: μv EEG frequency range: Hz
6 Chopper-stabilized LNA A chopper stabilized amplifier system consists of modulating and demodulating carriers with period T= 1/fchop, where fchop is the chopper frequency. DC servo loop uses for high pass filter and cancel residual offset Chopping reduces the DC input impedance of the sensing front-end. The low input impedance can result in attenuation of the weak input signals and degradation in noise performance
7 A fully differential chopper amplifier Chopping -> reduces the flicker noise Upmodulated flicker noise and offset show up as ripples at the output of the amplifier Sol :a parallel-rc impedance is added immediately after the 1st stage.
8 DC servo loop The EEG signal bandwidth is in the range Hz Pseudo-resistor larger than 100 GΩ in the feedback loop. Proccess variations (factor of 100). Duty-cycled resistors to enable high linearity and reliability
9 Impedance boosting Chopping reduces the DC input impedance of the sensing front-end -> Impedance boosting. Auxialiary path
10 Impedance boosting The auxiliary-path used charges the input caps Cin at the beginning of every chopping phase using aux-buffers reducing the charge provided by the input voltage, thus boosting Zin.
11 Impedance boosting Vin provides zero charge -> Problem : Amplification of aux-buffer offset and flicker noise
12 Impedance boosting Sol: Voff is up-modulated to fc/4 by using mixers M1 and M2 Voff creates a benign ripple instead of a DC offset. Storage capacitors Caux=8pF assist the aux-buffers at the beginning of the pre-charge phase. Higher input impedance without increasing power consumption
