Abstract
The diode stackup has been used as on-chip electrostatic discharge (ESD) protection for some applications in which the input/output signal swing is higher than VDD or lower than VSS. A novel ESD protection structure of diode stackup is proposed for effective on-chip ESD protection. Experimental results in 65-nm CMOS process show that the optimization on layout style can improve the ESD robustness, decrease the turn-on resistance, and lessen the parasitic capacitance of the diode stackup.
