Abstract :
This paper presents an efficient Monte-Carlo noise simulation method of ΣΔ modulators in time domain. It can be used to simulate thermal noise, dithering and other noise effects. The simulation is at circuit level, where comparators, opamps, resistors, switches, capacitors and other linear elements are used as building blocks. This method has been implemented in SIMthermal, a simulator written in Fortran77. Three simulation examples are given
