An integrated circuit including a first power rail, a second power rail, a power clamp connected between the first and second power rails; and a trigger circuit connected to the power clamp and the first second power rails. The trigger circuit includes an RC element formed on the basis of ...
Design of a Latchup-Free ESD Power Clamp for Smart Power ICs 摘要: A latchup-free design based on the lateral diffused MOS (LDMOS) adopting the "Darlington" approaches was designed. The use of Darlington configuration as the trigger circuit results in the reduction of the size of the circui...
反之,如果AC两点间ESD环路的Holding Voltage>Vclamp,ESD静电流优先通过Voltage Clamp Circuit进行泄放,带来失效风险。如果采用Rail Based ESD防护策略(端口二极管+GCNMOS Power Clamp)该结构会根据ESD的频率特性进行触发,可以一定程度避免ESD防护电路与钳位电路产生冲突的风险。但是笔者目前所接触到需要设计Voltage Clamp Circ...
In terms of ESD certification of an electronic circuit board, can you recommend a provider of this service in France? EMITECH is a French Lab. Can you tell something about protection during soldering (ie: solder connector wires to a board)?
前两个变容二极管被用作PD和NS模式的直接ESD路径,同时配合Clamp用作PS和ND模式。芯片可能通过某个地pin脚积聚了太多电荷,从而导致CDM损坏。When a CDM ESD event occurs, the circuit maybe damaged before the primary ESD protection circuit turns on, since a huge current level up to 10A could be reached...
发明人: YJ Huh 被引量: 13 摘要: An RC-triggered electrostatic discharge (ESD) power clamp circuit and method for providing ESD protection uses a control circuit with a latch to selectively activate a clamping transistor to discharge ESD on a first voltage rail to a second voltage rail.收...
(VSS) to become a quiescent current before the power clamp device turns on. So, the internal circuit of the zapped power domain and P+ guard-ring become a substrate triggering circuit to turn on the parasitic npn bipolar between two different power domains, resulting in most ESD current ...
D1B approaches 0V, and neither diode's leakage current affects the sensor's output signal. Depending on the polarity of an ESD event you apply to the circuit's input connector, its high-voltage spike discharges through diode D1A or D1B into the positive or the negative power-supply rail...

RC-triggered and MOSFET-based power supply ESD clamp circuits have been widely used to obtain the desired ESD protection ability. In this paper, a MOSFET-based ESD power clamp circuit with only10 ns RC time constant for 0.18-μm process is presented. A double pull-down path is proposed to...
