Bandwidth Estimation Using Short Circuit — Lesson 3

This lesson covers the bandwidth estimation techniques and the method of short-circuit time constants. It explains how to determine the bandwidth of a network by pulling out one capacitor and killing all other capacitors in the network. The lesson also discusses the method of open circuit time constants and how it helps to identify the zeros of a circuit. It further explains how to identify which capacitors contribute to poles and which contribute to zeros. The lesson concludes with the introduction of a new module on white band amplifier design and the challenges associated with handling circuits with both inductors and capacitors.
