Subject: Analogy Electronic and Circuit Derive Output Impedance & Voltage Gain for self bias un-bypass circuit using hybrid model

An operational amplifier consisting of three cascaded stages has a voltage gain of 3500. The gain of the first two stages is known to be -5 and -900. What is the voltage gain of the last stage and which type of MOSFET amplifier would you prefer for this stage?

Draw a circuit diagram of a Class-C power amplifier. Explain the reason why a Class-C power amplifier is in general more efficient than a Class-B power amplifier. What is the main disadvantage of Class-C power amplifiers?
