Abstract :
The paper presents, analyzes and simulates the behaviour of a variable-sampling-rate, third order, sigma delta modulator based on switched capacitor integrators. Theoretical study, as well as simulations carried out on the model, shows the possibility to reach a S/N ratio allowing 17 equivalent bit resolution
