| 2000 | Invention patented by Motohiko Morita and Kenji Maio on May 10th, 2000. Abstract: In a DA converter wherein an analog output voltage is formed in such a way that constant currents formed by a plurality of constant-current source transistors are selectively fed to a load resistor by controlling switching means to turn ON and OFF in correspondence with input signals; each of the constant-current source transistors is operated in an operating range from a saturation region to a non-saturation region as the output voltage enlarges in its absolute value, and those of the plurality of constant-current source transistors whose currents based on the operations in the non-saturation regions are selected by the switching means have their sizes enlarged so as to compensate for current decrements ascribable to such operations in the non-saturation regions. |
