ECT 2440 Study Guide - Final Guide: Biasing, Ford Bc-Series Transmission, Icq
Document Summary
Let"s start by reviewing the operating regimes of the bjt. Figure 1 along with the device schematic and relevant parameters. The characteristics of each region of operation are summarized below: cutoff region: Ic reaches a maximum which is independent of ib and . B-e junction is forward biased, c-b junction is reverse biased. We will focus on operation in the active region. In this region of operation the model of the. Large signal model of the bjt operating in the active region. The large signal model represents a simple state machine. The two states of interest are: b-e junction is forward biased, b-e junction is off, no current flows and the bjt is off. Volts, current flows and the bjt is on. We are interested in using the transistor as an amplifier with amplification a as shown on. For the generic bjt circuit the voltage transfer characteristic curve (output voltage versus input voltage) is shown on figure 4.
