Abstract
A digital/analog converter has a neuron MOS transistor, a maintenance circuit which keeps the drain potential of the neuron MOS transistor constant, and a current source. A linear dynamic range in terms of large signal is possible, so that converters having a larger input word size than, for example, only two bits can be realized in a simple way with low dissipated power. Such converters are of significance particularly for ULSI circuits.
