چکیده
AbstructSmall-signal Thevenin and Norton equivalent circuits seen looking into each terminal of the BJT and the FET are described. The application of these! circuits to writing by inspection the expressions for gain, input resistance, and output resistance of multistage amplifiers is demonstrated. The application of the circuits to the noise analysis of devices is illustrated by the calculation of the noise input voltage and current of the BJT and the noise input voltage of the MOSFET. The circuits are useful for the analysis of feedback amplifiers where Mason’s signal flow graph can he used to solve the simultaneous equations that are obtained. Several examples are presented which illustrate flow-graph solutions for feedback circuits.

The mixed-signal circuits with both analog and digital blocks on a single chip have wide applications in communication and RF circuits. Integrating these two blocks can cause serious problems especially in applications requiring fast digital circuits and high performance analog blocks. Fast switching in digital blocks generates a noise which can be introduced to analog circuits by the common su...
