Abstract :
The problems concerning the design of complex mixed-mode circuits are discussed. Complex analog circuits, using on-chip amplifiers, switched-capacitor techniques and digital control logic have to deal with noise on the power supply lines. This extra power supply noise can drastically decrease the performance of a system. Therefore interference aspects of power supply noise are discussed in two analog signal processing circuits: switched capacitor filters and opamps. Only by using building blocks with high power supply rejection ratios can high overall performances can be met
