Introducing Senior Undergraduate Students to the Open-Circuit Time-Constant Method for Circuit Analysis

Open-circuit time-constant (OCTC) method is an approximate analytical method to estimate the 3 dB bandwidth of baseband circuits. Considerable saving in computational effort is achieved since a full analysis of the circuit is not required. The paper focuses on teaching and illustrating OCTC to senior undergraduate students. Two examples are presented to highlight the benefits gained by the approximate analysis technique and the perception of the students on the subject.
