Abstract :
This paper describes applications of continuous-time feed-forward Sigma-Delta (ΣΔ) modulators to control DC-DC converters as follows. We propose to use continuous-time feed-forward ΣΔ controllers in DC-DC converters, and show that their transient response is faster than discrete-time and/or feedback-type ΣΔ controllers. We also show that second-order ΣΔ controllers have superior performance to first-order ones. SPICE and Matlab simulations substantiate these results.
