摘要
Electro-Static Discharge (ESD) protection circuit by parasitic lateral NPN bipolar transistors (LNPN) is used especially for NMOS Open Drain structure for signal Input/Output (IO) cell like Inter-Integrated Circuit (I2C) or Fail Safe IO. In power clamp, the LNPN is effective for very fast power ramp up case to avoid inrush current. In this paper, studies of good point and bad point are presented regarding the LNPN.
