摘要： A silicon controlled rectifier may be used to protect an integrated circuit from excessive voltage encountered during an electrostatic discharge (ESD) event. An ESD protected circuit may be conductively coupled to an anode of a first silicon controlled rectifier (SCR) and to an anode and gate of a second SCR disposed proximate and on the same substrate as the first SCR. A trigger current may be used to trigger and latch-up the first SCR in the event of an ESD. A stray current may develop in the substrate responsive to the first SCR latching-up. This stray current may cause a charge accumulation at an N-well (i.e., gate) of the second SCR and may be used to sympathetically trigger and latch-up the second SCR in the absence of an externally supplied trigger current to the second SCR.

摘要： Described is a low power clamp or driver comprising: an inverter; and a silicon controlled rectifier (SCR) embedded in the inverter such that the SCR is part of the inverter. The clamp offers improved conductance per area and lower leakage current compared to the traditional PMOS-based active rail clamps. The clamp or driver combines a trigger circuit with the inverter-embedded SCR for maximum area efficiency. The clamp or driver also result in less stringent requirements for power ramp rates.
摘要翻译：描述了一种低功率钳位或驱动器，包括：逆变器; 以及嵌入在逆变器中的可控硅整流器（SCR），使得SCR是逆变器的一部分。与传统的基于PMOS的主动轨道夹具相比，钳位提供了每面积更高的电导和更低的漏电流。钳位或驱动器将触发电路与逆变器嵌入式SCR组合，实现最大的面积效率。钳位或驱动器也对功率斜坡率有较不严格的要求。
