N2 - A practical solution has been proposed to safely apply the LVTSCR (low-voltage-trigger SCR) device for output ESD (electrostatic discharge) protection in the advanced submicron CMOS ASIC's without being accidentally triggered on in the noisy operating environments. By increasing the trigger current of the LVTSCR device up to 200 mA, a noise margin greater than VDD+12 V (VSS-12 V) against the accidental triggering due to the overshooting (undershooting) noise pulses has been practically confirmed by the experimental results. Due to remaining a lower trigger voltage, this solution can still provide effective ESD protection for output transistors but only occupies a small layout area.
