Bidyut K. Bose has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • CMOS Schmitt trigger circuit for TTL logic levels
    Patent number: 4563595
    Abstract: A CMOS Schmitt trigger circuit responsive to TTL logic levels is disclosed. A supply regulator circuit renders the circuit independent of temperature, supply voltage and device parameters.
    Type: Grant
    Filed: October 27, 1983
    Date of Patent: January 7, 1986
    Assignee: National Semiconductor Corporation
    Inventor: Bidyut K. Bose
  • Fast CMOS buffer for TTL input levels
    Patent number: 4430582
    Abstract: A CMOS integrated circuit is made compatible with TTL input signals. A regulator operates the CMOS gates in an array at a voltage that is slightly lower than the supply. The regulator sense circuit is made responsive to an operating gate and to a TTL bias reference. Accordingly, the regulator will compensate for changes in ambient conditions and manufacturing variations so that the gate array devices will reliably respond to TTL level switching signals.
