This thesis presents the design and simulation of a small, low-power, second-order, Δ-Σ (delta-sigma) modulator intended for use in multi-channel, portable systems where there is a need for digitizing biomedical signals such as Electro-Cardiogram (ECG), Electroencephalogram (EEG), or Electrocorticography (ECoG) waveforms. In particular, the modulator may, in the future, be fabricated
in a 0.5 µm CMOS process and used with a Brain-Controlled Interface (BCI) which uses an ECoG recording modality.
