- Provided are a current switch driving circuit generating a signal for driving a current switch, and a digital-to-analog converter using the same. The current switch driving circuit includes a first PMOS transistor in which a source terminal is connected to a power supply terminal, a gate terminal receives an input signal, and a drain terminal outputs a driving signal, an NMOS transistor in which a drain terminal is connected to the drain terminal of the first PMOS transistor, and a gate terminal receives the input signal, a second PMOS transistor in which a source terminal is connected to a source terminal of the NMOS transistor, a gate terminal is connected to a bias voltage terminal, and a drain terminal is connected to a ground terminal, and a control current source allowing the second PMOS transistor to be maintained constantly in an ON state.
