WebTranscribed Image Text: Problem 1: Figure shows a BJT biasing circuit with 3 =100, VBE = 0.7 V, VCESat = 0.2 V, and VB = 1 V. A) For Vc = 2 V calculate IB, Ic, and Rc. B) Find a new Rc for which the transistor stays at the edge of the saturation. Vcc 5 … WebMar 19, 2024 · Transistor Q 1 “pushes” (drives the output voltage in a positive direction with respect to ground), while transistor Q 2 “pulls” the output voltage (in a negative direction, toward 0 volts with respect to ground). Individually, each of these transistors is operating in class B mode, active only for one-half of the input waveform cycle.
WebMar 20, 2011 · For this reason, this tutorial will begin by biasing and analyzing a BJT differential amplifier circuit, and then will move on to do the same for a FET differential amplifier. But it should be noted that the procedures to analyze these types of differential amplifiers are virtually the same. BJT Differential Amplifier Web1.Fixed bias (base bias): The single power source (for example, a battery) is used for both collector and base of a transistor, although separate batteries can also be used. In the given circuit, Vcc = IbRb + Vbe. Therefore, IB = (Vcc − Vbe)/Rb. For a given transistor, Vbe does not vary significantly during use.
