Question

Find the answer (in Volts) to Question 2 in the attached image where:

VCC = 47 Volts, RC = 4.1 kOhms, RE = 2.1 kOhms,

VBE(sat) = 0.6 Volts, VCE(sat) = 0.2 Volts and

A = 1.0 Volts.

 

Provide your answer rounded to 2 decimal places.

Questions 1 - 3 Consider the circuit shown in Figure 1 where Vcc is a fixed voltage. The voltage at the base of the transistor, v (t), is a time varying waveform described by (1). v (t) = Vß + v₂ (t) Where VB is a DC offset and v (t) is a time varying, purely AC signal. Suppose the amplitude of v, (t) is A and we make the following assumptions: • The capacitor C is sufficiently large so that it can be considered to be a short circuit at the signal frequencies • Rc and RE are known • R» Rc • UBE=UBE (sat) • ß» 1 in the active region • VBE(sat) and VCE(sat) are known UB Vcc ww Rc C RE علیه R (1) Figure 1: Circuit for Questions 1 3. - Question 2 In addition to the assumptions outlined above, assume that Vcc is known. 1. Find the minimum value of VB required to ensure that the transistor re- mains in the active region at all times.
