Latest Patents
One of Shimatani's latest patents is a differential amplifying circuit. This circuit includes a first differential transistor pair, a second differential transistor pair, an adder section, and an amplifying unit. The first differential transistor pair receives first and second input signals along with an output signal as a third input signal. The second differential transistor pair also receives the first and second input signals and the output signal as a fourth input signal. The adder section combines the first output signals from the first differential transistor pair and the second output signals from the second differential transistor pair. The amplifying unit then amplifies the resultant signal from the adder section to output to the first and second differential transistor pairs.
Another notable patent is related to a display panel driver and display apparatus. In this design, an output amplifier circuit includes a first output stage that receives a power supply voltage and a first voltage lower than that, outputting a drive voltage in a defined range. The second output stage receives the power supply and ground voltages, outputting a drive voltage between these two. This innovative approach allows for flexibility in voltage settings, enhancing the performance of display technologies.
