An electrostatic discharge (ESD) protection circuit with novel structure based on a silicon-controlled rectifier (SCR) is proposed for 5 V ESD protection of integrated circuits. The proposed ESD protection circuit has large current driving capacity due to its low on-resistance and high ESD robustness in comparison with the conventional SCRbased ESD protection circuit. The conventional SCR-based ESD protection circuit and the proposed ESD protection circuit were fabricated using a 0.18 µm bipolar CMOS-double diffused metal-oxide semiconductor transistor (DMOS) process, and their electrical characteristics and ESD robustness were comparatively analysed using transmission line pulse measurements.

In Section I of the above article [1], the sentence beginning in the 18th line of the second column contains typos that misrepresent the range of voltages. The correct sentence is the following: "However, the strong snapback characteristics of a traditional SCR structure that are caused by high avalanche breakdown between the well regions allow it to have a substantially high trigger voltage (approximately 17-22 V) and low holding voltage (approximately 2-4 V)."

In this paper, dc-dc buck converter controled by the peak current-mode pulse-width-modulation (PWM) presented. Based on the small-signal model, we propose the novel methods of the power stage and the systematic stability designs. To improve the reliability and performance, over-temperature and over-current protection circuits have been designed in the dc-dc converter systems. To prevent electrostatic An electrostatic discharge (ESD) protection circuit is proposed. The proposed dc-dc converter circuit exhibits low triggering voltage by using the gate-substrate biasing techniques. Throughout the circuit simulation, it confirms that the proposed ESD protection circuit has lower triggering voltage(4.1V) than that of conventional ggNMOS (8.2V).
