Abstract A twice‐input variable‐resolution single‐side switching scheme without reset energy is proposed for successive approximation register (SAR) analogue‐to‐digital converters (ADCs). The proposed switching scheme is based on semi‐resting DAC technology to design a four‐array architecture capable of handling twice the swing of the signal input while reducing the capacitor array size. The technique of top‐plate sampling and monotonic shift is utilized so that no switching energy is generated for the first three comparisons. The proposed scheme utilizes full‐capacitor split, bridged switch, and C‐2C dummy capacitor technology, which reduces average switching energy consumption by 99.8% compared to conventional schemes and enables ADC variable resolution function, making the SAR ADC more suitable for IoT applications.
