FIGURE 4 shows an amplifier circuit. Write a short report on the operation and performance of the circuit. In completing the report you should:
- Explain the operation of the circuit and in particular the role of resistors R1 and R2.
- Build the circuit in PSpice and use it to determine:
(i) the quiescent value of Vout
(ii) the voltage gain for a 100 mV, 1 kHz , input signal
- Sketch the small-signal equivalent circuit of the amplifier and use it to estimate the voltage gain. Compare your answer with that of (ii) above.
- Attempt to calculate the quiescent value of Vout. Compare your answer with that given by the PSpice model. Try to explain any discrepancies.
An earth station receive antenna has a sky component temperature of20 K, a ground component temperature of 15 K . What is the total antenna noise temperature [K]
A single-loop negative feedback system has the loop transfer equation: L(s) = Gc(s)G(s) = K(s + 2)2 / (s(s2 + 1)(s + 8)) a. Sketch the root locus for 0 K infinity to indicate the significant features of the locus.
