D/A converter circuit and semiconductor device

Year	Description
2001	Invention patented by Yukio Tanaka and Munehiko Azami on November 20th, 2001. Abstract: A D/A converter circuit capable of handling a high bit number digital signal, having good linearity, and having a small occupied surface area is provided. The D/A converter circuit has n-m+1 capacitors (where m is a natural number, and smaller than n), and the supply and discharge of electric charge to one of the capacitors from among the n-m+1 capacitors are controlled by the lower m bits of a digital video signal. The supply and discharge of electric charge to the remaining n-m capacitors, from among the n-m+1 capacitors, are controlled by the upper n-m bits, from among the n bits, of the digital video signal.
