Introduction

Takashige Miyashita is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of circuit design, holding a total of 7 patents. His work focuses on enhancing the functionality and efficiency of electronic circuits.

Latest Patents

Miyashita's latest patents include a level shift circuit that effectively manages input and output signals. This circuit features a low voltage side circuit that receives an input signal and a high voltage side circuit that outputs a level-shifted signal. The low voltage side circuit incorporates a switching transistor that toggles between on and off states based on the input signal level. Additionally, a capacitor is connected in the current path, generating rush current when the transistor switches to the on state, thereby facilitating the output signal's level shift.

Another notable patent is an output limiting circuit designed for class D power amplifiers and audio equipment. This circuit includes a reference current generating portion that converts a constant voltage into a reference current using a resistor. It also features upper and lower side clip voltage generating portions that ensure the output signal remains within specified voltage limits. The gain adjusting portion of the circuit fine-tunes the operational amplifier's gain to prevent the output signal from exceeding these limits.
