Abstract
The settling behavior and power consumption of dynamic opamps are considered. The dynamic opamp is compared with a class A opamp for different clock frequencies. A single pole model in a closed loop configuration is used to estimate slewing and settling behavior. SPICE simulation results agree with theoretical predictions. It is shown that for the same power consumption dynamic opamps settle much faster than class A opamps. Dynamic opamps are particularly well suited for ultra low power switched-capacitor designs.
