A certain operational amplifier can supply an output current of ± 5 mA over an output voltage range of ±12 volts. Design a unity-voltage-gain stage that can be added to the output of the operational amplifier to increase the output capability of the combination to at least ±100 mA over a ± 10-volt range. Available power-supply voltages are ± 15 volts. Assume that complementary transistors with a minimum β of 50 and a power dissipation capability of 2.5 watts are available. A reasonable selection of low power devices is also available. Your design should include current limiting to protect it for shorts from the output of the stage to ground.
