Introduction

Takayuki Nakai is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of circuit design, holding a total of 4 patents. His work focuses on enhancing the functionality and efficiency of electronic circuits.

Latest Patents

Nakai's latest patents include an innovative AGC circuit. This circuit features a count control signal generating section that produces a count control signal based on the output of a variable gain amplifier. It also includes an up/down counter that performs counting operations according to the control signal. Additionally, a gain control signal generating section is responsible for supplying a gain control signal to the variable gain amplifier based on the count value. A state detector section outputs a state detection signal to indicate whether the circuit is in a steady state or another state. When the steady state is detected, the operation of the up/down counter and gain control signal generating section is controlled to fix the gain control signal.

Another notable patent is the charge pump circuit and electronic apparatus. This design incorporates a pumping capacitance and two drive transistors. The first drive transistor connects an input node to the pumping capacitance, while the second drive transistor connects the output node. In the charge storing mode, the first transistor is activated to store charge, and in the charge transfer mode, the second transistor transfers the stored charge to the output node. A protection circuit ensures that at least one of the transistors enters a high-resistance state based on the output voltage.
