Title: Kazuyasu Minami: Innovator in Current Detection and Amplifier Circuits
Introduction
Kazuyasu Minami is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of electronics, particularly in the development of current detection and amplifier circuits. With a total of 3 patents to his name, Minami's work showcases his expertise and innovative spirit.
Latest Patents
One of his latest patents is a current detection circuit. This circuit includes an N-type first transistor that supplies a first current to an output terminal. It also features an N-type second transistor that forms a current mirror circuit with the first transistor. A comparison circuit outputs a detection result indicating whether the first current exceeds a predetermined threshold based on the current flowing through the second transistor. Additionally, a ground fault detection circuit outputs a result that detects a ground fault at the output terminal. A logical circuit then provides a current detection signal indicating whether the first current is an overcurrent based on the results from the comparison and ground fault detection circuits.
Another significant patent is an amplifier circuit. This circuit consists of a first transistor and a first resistor connected in series between a power supply voltage and an output terminal. A second transistor and a second resistor are connected in series between the output terminal and a ground reference voltage. The circuit includes a first operational amplifier and a second operational amplifier. A first detection current is generated corresponding to the voltage drop across the first resistor, while a second detection current corresponds to the voltage drop across the second resistor. A first replication circuit subtracts the second detection current from the first detection current, and a third resistor conducts the resulting current.
