Abstract: This invention relates to a current cell playing a role as a current switch source in a digital-to-analog converter. According to the present invention, the current cell assembled by both p-type MOS transistor M1 for current supply and p-type MOS transistor M2 and M3 for symmetrical operation, comprises: an inverting means consisting of p-type and n-type MOS transistor M5 and M4, where the digital input signal Di is applied to each of gate terminal and where the source terminal is connected to power supply terminal Vdd and ground terminal GND; a transmission means consisting of n-type MOS transistor M7, where the digital input signal of Di is applied to its gate terminal and power supply voltage Vdd is applied to its source terminal, and p-type and n-type MOS transistors M6 and M8, where the digital input signal Di and the output signal of the said inverting means is applied to each of their gate terminal, respectively.
