Abstract :
An event-driven tracking analogue-to-digital converter (ADC) architecture is proposed. The proposed architecture has less sensitivity to amplifier and DAC nonlinearity, and reduces the swing and dynamic common-mode range requirement of the operational transconductance amplifier and comparators, respectively. The efficiency of the ADC is confirmed by detailed circuit simulations.
