Cascoded NPN electrostatic discharge protection circuit |
摘要 |
The electrostatic discharge protection circuit includes: at least two bipolar transistors Q1-Qn coupled in series; a top one Qn of the at least two bipolar transistors coupled to a protected node 10; a bottom one Q1 of the at least two bipolar transistors coupled to a common node 12; at least two resistors R1-Rn coupled in series; each of the at least two resistors is coupled to a corresponding base of one of the at least two bipolar transistors; and a bottom one R1 of the at least two resistors coupled between a base of the bottom one Q1 of the at least two bipolar transistors and the common node 12.
