In this dissertation a full custom Analog Front End (AFE) integrated circuit (IC) for an Electroencephalography system (EEG) is designed and implemented. The AFE consists of an ultra-low voltage amplifier and a Continuous-Time Σ∆ Analog-to-Digital converter (CT Σ∆ ADC). The AFE was implemented in 0.35 um CMOS process technology, and it works with a supply voltage of 0.5V.In order to provide a true low voltage operation, all the transistors are working in the subthreshold region. The proposed preamplifier's topology consists of an input stage based on a folded cascoded amplifier and an output stage based on a current source amplifier.The CT Σ∆ Modulator was selected to provide a very low power dissipation. The decimation stage is based in a ...
