Applications: A Variety of Circuits

Abstract

The method of driving point impedance/signal flow graphs for the analysis of analog circuits has been fully developed and extended to the specific analysis of the loop gain function for feedback circuits. In this chapter, we analyze a variety of circuits to fully demonstrate the application of the methodology. In addition, we extend the method to include examples of cells that transform the signal from one representation to another—the phase-locked loop and the switching regulators have cells that take a signal in one domain and output in another—phase to time in the pll, continuous voltage to pulse-width in the switching regulator. Most of these applications contain feedback, giving ample opportunity to analyze feedback effects in circuits with different topologies.
