PURPOSE: A voltage mirror circuit is provided to minimize a voltage error of a final output terminal by forming a current bias circuit, a monitoring resistor, and a terminator within one well. CONSTITUTION: A current bias circuit(200) includes the first and the second NMOS transistors(N1,N2), the first to the fourth PMOS transistors(P1-P4), and monitoring resistors(R1,R2) in order to apply the driving current to a current driver system(221). An output of an operational amplifier(210) is connected to each gate of the first and the second NMOS transistors(N1,N2). One terminal of the second resistor(R2) is connected to a negative input terminal of the operational amplifier(210). A bias voltage is applied to a positive input terminal of the operational amplifier(210).
