Design a cascade amplifier using smallest number

Reference no: EM13805459

Voltage amplifier stages having the characteristics show in the following table are available. The signal source has an open-circuit voltage of 20mV rms and an internal resistance of 2MΩ. The load is a 20Ω resistance. Design a cascade amplifier using smallest number of stages that provides at least 1 W to the load. What are the values of the input resistance, the output resistance and the open-circuit voltage gain of your amplifier?

Amplifier stage type	Open circuit Voltage gain	Input Resistance	Output Resistance
A	1	10 MΩ	1 kΩ
B	5	1 kΩ	1 Ω
C	10	20 kΩ	100 Ω
