Latest Patents

Kondou's latest patents include an innovative amplifier design. This amplifier features a first transistor with a gate terminal for input signals, allowing a current to flow based on the applied input. Additionally, a second transistor is connected to a load section, with its current dependent on the voltage change of the first transistor's drain terminal. The design incorporates a first resistance that connects the source terminal of the first transistor and the drain terminal of the second transistor, enabling current flow through both transistors. Furthermore, a third transistor supplies a current approximately equal to that of the second transistor, which is then output from an output end.

Another significant patent involves a power supply circuit that includes a charge pump circuit and a feedback circuit. This design addresses fundamental issues associated with voltage feedback type charge pump circuits. The power supply circuit features a charge pump circuit, a feedback circuit that feeds the output back to the input, and a first current source that maintains a constant current through the feedback circuit. A MOS transistor element and a resistor element are strategically placed within the feedback circuit, while a bias circuit applies a constant voltage to the MOS transistor's control terminal. The control section regulates the constant current flowing through the feedback circuit.
