Current cell driving circuit in digital-to-analog converter
The present invention relates to a current cell driving circuit in a digital-to-analog converter. The current cell driving circuit limits the potential of differential control signals to a given potential level by means of a voltage limiter using a parasitic capacitance of a transistor. Therefore, the present invention can effectively limit the potential of differential control signals DP and DN without compromising the power consumption and the circuit area and also can minimize the transfer time.
