Question

Use VEBactive = 0.7 V and beta = 100 for active mode. Use VEBsat = 0.7 V and VBCsat = 0.5 V for saturation. Assume that the transistor is in active mode. Follow the appropriate analysis to show if the transistor is in active mode or not. Assume that the transistor is in saturation. Follow the appropriate analysis to show if the transistor is in saturation or not. Do not use the results from part (a).

Explanation / Answer

a) It is in active mode , because Vb voltage is equal to zero. So, collector voltage > base voltage. b) For saturation condition, Vbe = 0.7 - 0.8 So, It is in saturation mode. And, |Vcesat| = 0.2V
