Latest Patents
Hamanishi's latest patents include an innovative operational amplifier design. This operational amplifier consists of a differential stage that receives two input signals, IN- and IN+, and outputs a signal NGP corresponding to the potential difference. The design features a level shift stage that processes the signal NGP and outputs a level-shifted signal NGN. The output stage amplifies the potential difference between the two input signals. The level shift stage is formed from a Differential Difference Amplifier (DDA), which maximizes the current drivability of a transistor in the output stage.
Another significant patent is his comparator circuit, which includes a feedback amplifier and a differential amplifier. This circuit is designed with input transistors that manage the feedback and stabilize the operating point of the differential amplifier. The timing for feedback is crucial, occurring when the outputs of the differential amplifier are nearly equal, ensuring optimal performance.
