摘要： In one embodiment, the invention is an integrated circuit (IC) including an OTP memory and conditioning circuitry. The IC receives an externally-generated DC programming voltage signal that the conditioning circuitry transforms into a programming pulse signal for programming the OTP memory. The conditioning circuitry includes: (i) reset protection circuitry for holding the programming pulse signal low if the IC is powering up, (ii) an overvoltage protection circuit for substantially preventing the programming pulse voltage from exceeding predefined boundaries, and (iii) a conversion switch for controlling the programming pulse voltage. The programming pulse voltage is (i) substantially equivalent to the externally-generated DC voltage if an enable signal is on, and (ii) substantially equivalent to a reference voltage if the enable signal is off.

摘要： An ESD protection circuit includes a first voltage clamp, connected between a first voltage supply node and a second voltage supply node of the circuit, and a second voltage clamp, connected between the second voltage supply node and a voltage return of the circuit. The first voltage supply node is adapted to receive a first voltage which is greater than a prescribed gate oxide reliability potential of the circuit. The second voltage supply node is operative to receive a second voltage which is less than the first voltage. The first voltage clamp is operative to clamp the first voltage on the first voltage supply node to a first value during an ESD event between the first and second voltage supply nodes, and the second voltage clamp is operative to clamp the second voltage on the second voltage supply node to a second value during an ESD event between the second voltage supply node and the voltage return.

摘要： An ESD protection circuit for protecting a circuit from an ESD event occurring between a first voltage supply node and a second voltage supply node associated with the circuit to be protected includes an MOS device having a gate terminal, a first source/drain terminal and a second source/drain terminal. The first source/drain terminal is connected to the first voltage supply node and the second source/drain terminal is connected to the second voltage supply node. The ESD protection circuit further includes a trigger circuit coupled to the gate terminal of the MOS device. The trigger circuit is configured to generate a control signal at the gate terminal of the MOS device for activating the MOS device during the ESD event. At least a portion of the trigger circuit is formed in a floating well which becomes biased to a voltage that is substantially equal to a first voltage when the first voltage is supplied to the first voltage supply node or to a second voltage when the second voltage is applied to the second voltage supply node, whichever voltage is greater.

摘要： A voltage level translator circuit is selectively operable in one of at least two modes in response to a control signal. In a first mode, the voltage level translator circuit is operative to translate an input signal referenced to a first source providing a first voltage to an output signal referenced to a second source providing a second voltage. In a second mode, the voltage level translator circuit is operative to provide a signal path from an input of the voltage translator circuit to an output thereof without translating the input signal. The control signal is indicative of a difference between the first voltage and the second voltage.

摘要： The present invention provides, in one embodiment, an integrated circuit having a substrate and active devices formed on the surface of the substrate. Other embodiments of the integrated circuit provide for having at least either three or four metal layers. In a particular embodiment of the present invention, the integrated circuit comprises a bond pad formed over a portion of the active devices. The bond pad has a footprint. As used therein the word footprint means the area covered by the device to which the word refers. The integrated circuit further incudes a patterned metal layer having a metal layer footprint that is located between the bond pad and the substrate and a built-in self-test (BIST) circuit that has a BIST footprint, which is located between the substrate and the bond pad. In this particular embodiment, the bond pad footprint overlays at least a portion of the metal layer footprint and the BIST footprint. However, in a more advantageous embodiment, the bond pad footprint overlays a substantial portion of the metal layer footprint and the BIST footprint.
