Abstract

This paper describes the design and fabrication of a digital volume control integrated circuit which replaces a mechanical volume control. The integrated circuit can be controlled volume by up/down switch. It has been fabricated by SST bipolar standard process. Its chip size is 2.5x2.5 mm\ulcorner As a result, we succeeded in fabrication of integrated circuit which satisfied DC characteristics and proper operation of volume control.
