Short Description

Delta-sigma based converters have been the topology of choice for many high performance applications such a medical imaging since several years due to their high dynamic range and high linearity. More recently the main implementation technique has changed from discrete-time switched capacitor to continuous-time, RC based structures, because they offer implicit filtering, do not need as much buffering in front and can be realized with less power consumption. In this thesis a continuous-time delta-sigma modulator for up to 5MHz bandwidth and 80dB SNDR will be investigated first at behavioral level, followed by a circuit design in 130nm CMOS. It will be possible to learn the whole the design cycle including system simulation and layout as a master student.
