1. An output driving circuit, comprising:
a plurality of bias voltage generating circuits configured to generate a plurality of bias voltages;
a switching control circuit; and
an output voltage generating circuit,
wherein the switching control circuit is configured to selectively connect one bias voltage generating circuit of the plurality of bias voltage generating circuits to the output voltage generating circuit based on an output voltage, and
wherein the output voltage generating circuit is configured to transmit and receive a parasitic current generated due to transition of the output voltage to and from the one bias voltage generating circuit selectively connected to the output voltage generating circuit through the switching control circuit.
