ABSTRACT:
A D/A converter utilizing a redundant binary expression includes a current supplying circuit and a current decreasing circuit operating responsive to each bit in the signal expressed in the redundant binary expression. The current supply circuit and the current decreasing circuit have their outputs connected together while their current driving capacities are established in response to the functions of the powers of 2 for each bit. In this manner, this D/A converter is able to convert the data signals expressed in the binary redundant expression directly into analog signals.
