In a Single Input Balanced Output Differential amplifier, given VCC=15v, RE = 3.9k?, VCE=2.4 v and re=250?. Determine Voltage gain

Question

Quizplus · Accepted Answer

The voltage gain (Av) of a differential amplifier in a single input balanced output configuration can be calculated using the formula Av = -Rc/(2re + RE). However, the given information does not directly provide Rc, but we can infer it from VCC and VCE. Given VCC = 15V and VCE = 2.4V, and assuming the transistor is in active mode, the collector current (Ic) and emitter current (Ie) can be approximated to be the same due to the transistor's operation. However, without the collector resistor (Rc) value or the collector current (Ic), we cannot directly calculate Rc from the given information. The formula for voltage gain in the question context seems to be misapplied or missing critical information for direct calculation. In a typical scenario, if we had the collector resistor value or could calculate it, and assuming the question intends for a simplified approach ignoring the role of RE in the internal emitter resistance (re') calculation, the voltage gain (Av) formula for a single input balanced output configuration simplifies to Av ≈ -Rc/re, where re is the intrinsic emitter resistance. Given re = 250Ω, without Rc, we cannot proceed directly. However, assuming a misunderstanding in the question's presentation and that it intended for a simplified direct calculation or provided incorrect parameters for the typical formula application, one might attempt to use an approximation or a different formula based on the provided values. In educational contexts, it's crucial to ensure the question aligns with the expected formula and provided parameters. For a more accurate response or calculation, additional information or clarification on the intended formula and parameters (like Rc or the correct approach to calculate Av with the given values) is necessary.
