Latest Patents
Mori's latest patents include innovative technologies aimed at improving the accuracy and efficiency of D/A converters. One of his patents focuses on a method for comparing circuits and offset compensating apparatus. This invention involves a switch connected to the 'a'-terminal side, where the offset of a differential output voltage 'A−' of a D/A converter is held in a comparator and reflected to a reference voltage. The switch is then switched to the 'b'-terminal side, allowing for the measurement of the offset of a differential output voltage 'A+' of the D/A converter. An error signal is outputted to a counter, which counts up the value, and this operation is repeated to determine an offset correction value.
Another significant patent by Mori is for a comparator with an offset canceling function and a D/A conversion apparatus that can cancel input/output offsets with high accuracy. This invention addresses the unbalance between right and left currents of the differential circuit by inverting the phase of a single-end output signal and feeding it back to one substrate of the differential pair MOS transistors. This adjustment changes the threshold voltages of the MOS transistors and fine-tunes their current capacities.
