An apparatus for generating a resolver excitation signal and a vehicle including the same are provided. The apparatus includes an input portion that is configured to receive an input signal and a current amplifier that is configured to generate an output signal by amplifying the input signal and that has a circuit protector that protects a circuit from an overcurrent. An output portion is configured to output the output signal. Additionally, the circuit protector includes a first transistor that has an emitter connected to the output portion, a second transistor that has a collector connected to the output portion and a base connected to a base of the first transistor and a rectifier connected to a base of the first transistor and the base of the second transistor.
