Title: Nami Inamasu: Innovator in Digital-to-Analog Conversion Technology
Introduction
Nami Inamasu is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of digital-to-analog conversion technology. With a total of 2 patents to his name, Inamasu continues to push the boundaries of innovation in this area.
Latest Patents
Inamasu's latest patents include a digital-to-analog converter circuit designed for the reduction of component elements. This innovative circuit converts a digital input signal, consisting of high-order bits and low-order bits, into an analog output signal. The circuit features a first digital-to-analog converting circuit that produces a first current corresponding to the value represented by the high-order bits. Additionally, it includes a memory circuit that stores error data information for each value represented by the high-order bits. An arithmetic circuit performs operations on the low-order bits and the error data to produce amended low-order bits. A second digital-to-analog converting circuit then generates a second current based on these amended low-order bits. Finally, an analog adder combines the first current, weighted by a predetermined factor, with the second current to yield an analog output signal that accurately reflects the digital input signal.
Another notable patent by Inamasu is a digital-to-analog converter that divides a digital signal into upper and lower bits, converting them into first and second analog signals, respectively. This converter incorporates means for adding a predetermined value to the lower bits, with a carry signal applied to the upper bits during the addition. The controlled upper and lower bits are then converted into separate analog signals, which are subsequently combined to produce a final analog signal after the second analog signal is attenuated based on the number of lower bits.
