    摘要: In an ESD protection device making use of a LVTSCR, at least one contacted drain and at least one emitter are formed, and are arranged laterally next to each other to be substantially equidistant from the gate of the LVTSCR, to improve holding voltage and decrease size. The ratio of emitter width to contacted drain width is adjusted to achieve the desired characteristics.

    摘要: An ESD protection circuit that can be easily configured to provide ESD event protection against a range of ESD event voltages. The circuit is also compatible with high frequency ICs. The ESD protection circuit includes an input terminal configured to receive an ESD event signal and a diode sub-circuit. The diode sub-circuit includes at least one diode (e.g., either a single diode or a plurality of diodes connected in series or parallel configuration), a diode input node and a diode output node. The diode sub-circuit is configured to receive an ESD event signal from the input terminal and to operate under forward bias conditions to provide a diode output signal at the diode output node. The circuit also includes a bipolar junction transistor (e.g., a Si—Ge bipolar junction transistor) with a base, a collector and an emitter. The emitter is configured to receive the ESD event signal from the input terminal, while the base is configured to receive the diode output signal from the diode output node. A resistor, with a resistor input node, a resistor output node and an output terminal, is also included in the circuit. The resistor input node is electrically connected to the diode output node and the output terminal is connected to the resistor output node, the emitter and ground. By predetermining the electrical characteristics (e.g., forward bias voltage) and number of diodes in the diode sub-circuit, the circuit can be adapted to provide ESD protection against a range of ESD event voltages.

    摘要: The holding voltage (the minimum voltage required for operation) of a triac is increased to a value that is greater than a dc bias on to-be-protected nodes. The holding voltage is increased by inserting a voltage drop between each p+ region and a to-be-protected node. As a result, the triac can be utilized to provide ESD protection to power supply pins.

    摘要: A MEMS magnetic flux switch is fabricated as a ferromagnetic core. The core includes a center cantilever that is fabricated as a free beam that can oscillate at a resonant frequency that is determined by its mechanical and material properties. The center cantilever is moved by impulses applied by an associated motion oscillator, which can be magnetic or electric actuators.
