Latest Patents

Takeuchi holds a patent for an isolator circuit with improved frequency response. This isolator circuit is designed to accept an input current and generate a corresponding output current that is isolated from the input. The circuit utilizes a core that develops a flux in response to the input current, along with a feedback winding that carries the isolated output current. A magneto-sensitive element, such as a Hall effect element, responds to the flux in the core. An amplifier receives the output from the magneto-sensitive element and supplies a current to the feedback winding to cancel the flux produced in the core due to the input current. The design includes a compensation winding that responds to the difference between the flux produced by the input current and the output current, thereby improving the frequency response of the circuit.
