The fundamentals of designing digital-analog signal processing systems

摘要

Methods of modeling digital-analog systems with switched capacitors in the time and frequency domains are outlined. Models for taking into account resistive components and frequency-dependent amplification gains of operational amplifiers are described. Algorithms for constructing the equations of such systems, difference state equations, and a new method of state variables, whose variables are increments of the charges in capacitors, are proposed. The main stages of designing such systems are considered.
