  • Systems and methods for providing bi-directional signal level shifting
    Patent number: 11101789
    Abstract: A bi-directional level shift circuit shifts signal levels between a first signal line and a second signal line. The circuit includes a first transistor and a second transistor. The first transistor includes a first gate connected to the second signal line, a first source connected to the first signal line, and a first drain connected to a voltage rail which supplies voltage. The second transistor includes a second gate connected to the voltage rail, a second source connected to the first signal line, and a second drain connected to the second signal line.
    Type: Grant

  • System and method for testing devices sensitive to magnetic fields
    Patent number: 6381716
    Abstract: A high permeability magnetic core structure introduces a magnetic field to an intergrated circuit during testing. The magnetic core is mounted in an automatic tester and is integrated into the mechanical test site assembly that holds the integrated circuit in place during testing. Wound wire coils, mounted on the core structure, generate the magnetic field that is used for the test.
