Weba) An NPN transistor has a DC current gain β=100, calculate the base current required to give a collector current of 5 mA. b) Sketch the Schematic diagram of a Class A, 2N2222 NPN common emitter amplifier. Use R1=12k and R2=1.5k as bias resistors, Rc=2k. Choose a suitable value for RE, the emitter resistor. WebThe collector current is whatever we require or choose. It could range from micro-Amps to Amps depending on the application and transistor rating. We choose IC = 1mA, typical …

WebAn exact numerical solution in one step is not possible (because of the exponential function). However, the two following alternatives exist: (a) Iterative solution: Start with VBE=0.65 volts and verify - using both functions - if this value was … Web- Consider a uniformly doped silicon npn bipolar transistor with the following parameters: N B = 5× 1016 cm−3,N C = 2×1015 cm−3,DB = 25 cm2/s,xBo = 0.7μm. Assume that xBo ≪ LB and that V BE = 0.60 V. The collector-base voltage is in the range 2 ≤ V CB ≤ 10 V. Neglect I pco (I C = I nC +I pco ≅ I nC).
