| Sumario: | This thesis presents a mixed signal methodology for the design and verification of an incremental ADC and digital filter to be used in Li-Ion battery management systems. Incremental ADCs are a type of Nyquist rate converters based on sigma delta modulation, which exploits oversampling to achieve high resolution with relaxed matching requirements for passive components. These converters are specially suited for multiplexed systems since modulator and filter are periodically reset, making them ideal for battery management systems where several channels are measured. The design in this thesis will be based on a pre-existing ADC system. The digital filter architecture will be changed to enable a faster conversion rate, while maintaining the error specification. |
