WebAug 16, 2024 · If you try and "brute-force" the collector down to the emitter voltage, the normally reverse-biased BJT base-collector region becomes forward biased and the current gain plummets. After all, the base-emitter region is forward biased and, if collector drops close to emitter then that region is also forward biased thus ruining hFE. WebELE200 Laboratory SMALL-SIGNAL BJT AMPLIFIERS OBJECTIVES 1) To understand the operation of the common-emitter (CE) amplifier 2) To learn the effect of a bypass capacitor on amplifier voltage gain (Av) THEORY Transistor A transistor is a non-linear, active three-terminal device that acts as a voltage-to- current converter. WebDynamic input resistance is defined as the ratio of change in input voltage or base voltage (VBE) to the corresponding change in input current or base current (IB), with the output voltage or collector voltage (VCE) kept at constant.
