Abstract :
Sigma-Delta modulation is a very efficient technique for analog to digital conversion. In this paper the realization of second order Sigma-Delta modulators is considered, both with switched capacitor and active RC circuits. The resulting modulators are realized using discrete components and their performance is evaluated and compared
