| 2000 | Invention patented by Hirokazu Yoshizawa on October 26th, 2000. Abstract: In a pipeline A/D converter circuit, the time at which outputs of MDACs of the A/D converter circuit change is shifted at respective stages, so that a cumulative error is avoided. In a resistance ladder circuit for supplying reference voltages to sub-A/D converter circuits of the pipeline A/D converter circuit, main resistors and auxiliary resistors are alternately connected in series to prepare the reference voltages, and the reference voltage supplied to the first stage MDAC is made different from the reference voltage supplied to the second and subsequent stage MDACs. In an embodiment, the auxiliary resistors have a resistance value of no more than one-half that of the main resistors to provide the offset. |
