Title: Integration system d/a conversion circuit
Inventor: ISO YOSHIMI
IPC: H03M1/10
Filed: 1990-05-18
Abstract: PURPOSE:To prevent an conversion linearity from deteriorating due to the error of a current ratio control by inputting a numeric value after substracting 1 from a midpoint data when the midpoint data is inputted to a high-order counter and operating a low-order counter in one more cycle. CONSTITUTION:Control circuits 41-43 and two 6 bit counters 22 and 23 which have one more bit at the high-order side are provided. When the midpoint data to be inputted to the high-order counter is '10', the data is converted to the value after substracting 1 from this, that is, '01' and inputted to the high-order counter. Then, the low-order counter has one more bit at the high- order side so as to be 3 bit counter and 1 is inputted to this most significant bit so that the low-order counter can operate in one more cycle and indicate a prescribed conversion character. Thus, it is possible to realize the sufficient linearity without clipping.
