I keep getting the wrong answer from everyone else pls help me
get the right answer
For the BJT bias circuit shown, what value of Rc in kilohms is needed to allow the maximum possible peak-to-peak signal swing on the collector without clipping? Use Vcc-9V, Vee--7V, Vb-1.2V, and Re -9.9k2. Assume that to keep the transistor in the forward-active region, the base-collector junction cannot be forward biased. Use B 20 and Vbe(on) 0.7V. Neglect the effects of base-width modulation. Vcc...
Experiment 2: Good biasing Set up the circuit with R2 12 k2, R RE 1 k, and Vcc 15 V 39 k2, Rc = 2 k?. Circuit Analysis: Compute Ic, I, and VCE PSpice Simulation: a) Simulate the circuit with PSpice (bias point details only) and compare values of Ic, IB, VCE, and VBE from PSpice simulations with your analytical calculations. b) Rerun your PSpice simulations for temperatures of 0 and 60°C. Make a table of Ic IB, VCE, and...

Kind of goes without saying but if you have no knowledge than dont
comment or try and answer this question you dope
Questions 1-3 below are about the amplifier circuit of Figure 1. Here Vcc is a fixed voltage The base voltage vB(t) is time-varying, and is of the form vB(t) V(t) where VB is a DC offset, and vb(t) is a time-varying purely AC signal. Suppose the amplitude of vb is A. Assume that the capacitor C is...
Consider the npn BJT with a turn-on voltage V1 = 0.70 V, and a saturation emitter-collector voltage V CE/SAT) = 0.20 V. (a) [20 points) Consider this transistor in a common- emitter circuit (Re = 0). Design this common- emitter circuit to produce the IV (Ic vs. VCE) characteristic and load line (LL) as shown in the graph. Your answers are the following: a drawing of the circuit; the values of Vcc, Rc, VBB, and Ra; and the value for...
(2+5 pts) Consider the bias circuit below for a transistor amplifier designed for active region operation. The desired bias point parameters are lg = 3 mA and Ic = 2.97 mA. Assume VBE- 0.7 V and VT=25 mV. Determine the emitter voltage VE . Choose the best answer. VCC +15 V Vc RBB VB LVE V BB RE 500 S2 1.49 V O2v 01.5V O 0.7V
Could someone please help me on how I should be configuring the
circuit in Figure 4(a) in Multisim? Basically not understanding
question #1 in the Procedure. Cannot keep Vrb the same value while
adjusting Vcc. Then when trying to adjust Vbb to hold Vrb, Ib
changes.
Any help is appreciated!

4. Lab VIII: Experiment VII The Bipolar Junction Transistor (BJT) Characteristics The bipolar junction transistor (BJT) is a three-terminal solid state device widely used as an amplifier (or switching) device. It consists of two n-type materials sandwiched by p-type material (npn) or two p-type and n-type. The terminals (sections) are known as emitter E, base B and collector C. Two currents and two voltages uniquely describe the behavior of the device. The third current/voltage can be determined through KCL/KVL. See...
