Abstract:
This thesis presents a novel algorithmic A/D converter to be used in a biosensor.
The converter is capable of a conversion rate of 1.5 bits/phase and hence the
required conversion time is reduced. The proposed architecture is analyzed for non-ideal
effects and compared with existing algorithmic A/D architectures. The
converter needs only one op-amp, 4 comparators and 3 capacitors. Power reduction
techniques are discussed with respect to the biosensor and the ADC. The ADC is
designed for fabrication in a CMOS 0.18μm process.
