Abstract
A multiplying digital-to-analog converter (MDAC) with capacitive load reset on an operational amplifier and a pipeline analog-to-digital converter using the MDAC are disclosed. The MDAC includes an operational amplifier and first and second switched-capacitor networks sharing the operational amplifier. The operational amplifier is further coupled with first capacitive load cells when the first switched-capacitor network is coupled to the operational amplifier, and the first capacitive load cells are reset when the first switched-capacitor network is disconnected from the operational amplifier. The operational amplifier is further coupled with second capacitive load cells when the second switched-capacitor network is coupled to the operational amplifier, and the second capacitive load cells are reset when the second switched-capacitor network is disconnected from the operational amplifier.
