Title: ESD tutorial basic (HBM, power clamp)
Post by liletian on Apr 9^th, 2018, 10:53am

Hi Guys

I am wondering if anyone can provide some ESD tutorials about the power clamp, back to back diode and HBM model etc.

Best regards,

I think you can find the basic introduction from your technology files. I think every foundry will introduce this part to guide the design to avoid ESD and latchup problems.

Best regards,

The Power clamp is GGNMOS or SCR, the back to back diode is supposed to be used between DGND and AGND.
1),The GGNMOS is very effective and robust, the scr is used carefully for latch-up characteristci.
2),back to back diode is used to the noise and ESD ability
3),the HBM model is the test model or simulation model?
the HBM test model are componet and system
the HBM simulatiom model often refer to tlp , there is few spectre simulatiom mode except the mos discharge through mos channal
