Abstract
Two different approaches to transform a discrete-time sigma-delta modulator into a continuous-time system with an arbitrary feedback waveform are presented. Taking the real shape of the feedback pulse into account at system-level allows one to adjust the modulator coefficients in order to compensate for the circuit nonidealities
