摘要： Apparatus and methods for electronic circuit protection are disclosed. In one embodiment, an actively-controlled protection circuit includes a detector, a timer, a current source and a latch. The detector is configured to generate a detection signal when the detector determines that a transient signal satisfies a first signaling condition. The timer is configured to receive the detection signal, and to generate a current control signal. The current control signal is provided to a current source, which produces a trigger current at least partly in response to the control signal. The trigger current is provided to a node of the latch, thereby enhancing the conductivity modulation of the latch and selectively controlling the activation voltage of the latch.

摘要： Symmetrical/asymmetrical bidirectional S-shaped I-V characteristics with trigger voltages ranging from 10 V to over 40 V and relatively high holding current are obtained for advanced sub-micron silicided CMOS (Complementary Metal Oxide Semiconductor)/BiCMOS (Bipolar CMOS) technologies by custom implementation of P1-N2-P2-N1//N1-P3-N3-P1 lateral structures with embedded ballast resistance 58, 58A, 56, 56A and periphery guard-ring isolation 88-86. The bidirectional protection devices render a high level of electrostatic discharge (ESD) immunity for advanced CMOS/BiCMOS processes with no latchup problems. Novel design-adapted multifinger 354/interdigitated 336 layout schemes of the ESD protection cells allow for scaling-up the ESD performance of the protection structure and custom integration, while the I-V characteristics 480 are adjustable to the operating conditions of the integrated circuit (IC). The ESD protection cells are tested using the TLP (Transmission Line Pulse) technique, and ESD standards including HBM (Human Body Model), MM (Machine Model), and IEC (International Electrotechnical Commission) IEC 1000-4-2_standard for ESD immunity. ESD protection performance is demonstrated also at high temperature (140° C.). The unique high ratio of dual-polarity ESD protection level per unit area, allows for integration of fast-response and compact protection cells optimized for the current tendency of the semiconductor industry toward low cost and high density-oriented IC design. Symmetric/asymmetric dual polarity ESD protection performance is demonstrated for over 15 kV HBM, 2 kV MM, and 16.5 kV IEC for sub-micron technology.

摘要： A high-voltage, low-leakage, bidirectional electrostatic discharge (ESD, or other electrical overstress) protection device includes a doped well disposed between the terminal regions and the substrate. The device includes an embedded diode for conducting current in one direction, and a transistor feedback circuit for conducting current in the other direction. Variations in the dimensions and doping of the doped well, as well as external passive reference via resistor connections, allow the circuit designer to flexibly adjust the operating characteristics of the device, such as trigger voltage and turn-on speed, to suit the required mixed-signal operating conditions.

摘要： A complementary SCR-based structure enables a tunable holding voltage for robust and versatile ESD protection. The structureare n-channel high-holding-voltage low-voltage -trigger silicon controller rectifier (N-HHLVTSCR) device and p-channel high-holding-voltage low-voltage -trigger silicon controller rectifier (P-HHLVTSCR) device. The regions of the N-HHLVTSCR and P-HHLVTSCR devices are formed during normal processing steps in a CMOS or BICMOS process. The spacing and dimensions of the doped regions of N-HHLVTSCR and P-HHLVTSCR devices are used to produce the desired characteristics. The tunable HHLVTSCRs makes possible the use of this protection circuit in a broad range of ESD applications including protecting integrated circuits where the I/O signal swing can be either within the range of the bias of the internal circuit or below/above the range of the bias of the internal circuit.
