Which of the following is the basic feature of the emitter-connected amplifier circuit? I. It has voltage gain II. It has current gain III. There is a 180 degree phase difference between the input signal and the output signal

4) Below is the small signal model of a multistage amplifier. Using this model, write the equationsthat you would need to determine the voltagegain. IMPORTANT: You only need to providethe equations that you would need to determinethe voltage gain. You DO NOT need to combine and simplify the equationsto determine a final expression for the voltagegain. Vin Vo Vb vo1 Rb R13 Vbe1 Vbe2 'e gm 1 Vbe1 gm 2 Vbe2 Rc2 Rc1 Re
