Improved design techniques for low-voltage low-power switched-capacitor delta-sigma modulators

Grilo, Jorge 27 June 1997 (has links)
This dissertation investigates the constraints which arise when switched-capacitor (SC) delta-sigma modulators are designed for low-voltage operation, targeting also low power dissipation, and proposes methods of improving the performance and optimizing for low power dissipation. This is accomplished by identifying critical elements whose performance can lead to increased power dissipation, as well as the fundamental limitations of available analog circuit techniques. A prototype was designed and fabricated, which reflected these findings, and therefore exhibited good performance and nearly optimum power dissipation. One of the key performance parameters is the dc gain of the amplifier in the first stage; it should be high. This is necessary for high linearity and low quantization noise leakage. In low-voltage operation, it may become impractical to use conventional topologies employing cascoding techniques (e.g., folded-cascode) which provide high gain in one single stage. Rather, cascaded structures have to be used. The disadvantage of the latter is the necessity for frequency compensation which results in increased power dissipation. Hence, another objective of this work is to exploit techniques which compensate for the open-loop gain characteristic of the amplifier (dc gain and nonlinearity), thus permitting the utilization of single-stage low-gain topologies. Predictive correlated double sampling is one of such techniques and is analyzed in detail. / Graduation date: 1998
