GATE ECE on Transistor's Practice Test - 2

  1.    A Bipolar Transistor is Operating in the active region with a collector current of 1mA. Assuming that the β of the transistor is 100 and the thermal Voltage (V_t) is 25mV,the trans conductance(g_m) and the input resistance (r_π) of the transistor in the common emitter Configuration, are
