a) The amplifier shown in Figure 4a has been designed to have the operating point: Ic = 2 mA, VCE = 4 V, where Ic is the collector current and VCE is the collector-emitter voltage. Vcc = 15 V Rc = 1.5 k2 R1 Vout Vin R2 RE GND = 0 V %3D Figure 4a. i) Determine the values for the resistors R1, R2 and RE that would meet this requirement. ASsume VBE = 0.7 V, and B= 200. ii) Draw an a.c. small signal equivalent circuit for the amplifier using an h (hybrid) parameter model for the transistor in Figure 4a. State the name and unit of each parameter of the model. Assume the capacitors are short circuits at the frequencies to be used. iii) Using your small signal model calculate values for the input resistance, output resistance and voltage gain of the amplifier. Assume hie = 1 k2 and he = 200.
