As IoT is increasingly integrated into our everyday life, the demand for different sensor modalities, especially imaging, is rising. IoT imagers are often compact and have small form-factor batteries and thus must be designed with both low power (imp

The switched-capacitor SAR architecture has benefited tremendously from technology scaling. We first present a charge-injection-based SAR architecture that shrinks the die area needed for a SAR ADC and achieves outstanding energy efficiency. We go on
