The correct answer is: A. Push-pull
A push-pull configuration is a type of electronic circuit that uses two transistors to drive a load. The transistors are arranged in such a way that one transistor is always on and the other is always off. This allows the circuit to provide a high current output with a low voltage drop.
A totem pole configuration is a type of electronic circuit that uses two transistors to drive a load. The transistors are arranged in such a way that one transistor is always on and the other is always off. This allows the circuit to provide a high voltage output with a low current drop.
Active high is a type of logic gate that uses a high voltage to represent a logic 1 and a low voltage to represent a logic 0.
Active low is a type of logic gate that uses a low voltage to represent a logic 1 and a high voltage to represent a logic 0.
In a BICMOS circuit, the BJTs are used in a push-pull configuration. This allows the circuit to provide a high current output with a low voltage drop.
