Title: Tomohiko Sugimoto: Innovator in Amplifier and Switched Capacitor Circuits

Introduction

Tomohiko Sugimoto is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of electronics, particularly in amplifier and switched capacitor circuits. With a total of 9 patents to his name, Sugimoto continues to push the boundaries of innovation in his field.

Latest Patents

Among his latest patents, Sugimoto has developed an amplifier circuit that includes a sampling circuit and an amplifier connected to the output of the sampling circuit. This innovative design features a feedback capacitor positioned between the output terminal of the amplifier and the output terminal of the sampling circuit. Additionally, a quantizer, which includes a comparator, is configured to quantize the voltage at the output terminal of the sampling circuit. This quantizer outputs a digital code based on the voltage comparison, which is then processed by a control circuit that stores the digital code as a cancellation digital code. A digital-analog (D/A) converter subsequently outputs an analog signal in accordance with the digital codes from the control circuit.

Another notable patent is his switched capacitor circuit, which comprises a first sampling circuit with a first sampling capacitance element. This circuit receives an input voltage and outputs a sampled voltage based on a first sampling operation. The quantizer in this circuit quantizes the sampled voltage and outputs a corresponding quantized value. A digital-to-analog converter then outputs an analog signal based on this quantized value. Furthermore, a first logic circuit initiates the sampling operation of a second sampling circuit when the quantizer completes its quantization process.
