This paper presents a novel silicon controlled rectifier (SCR)-based ESD protection device with a low trigger voltage and high robustness for I/O clamp. The low trigger voltage is achieved by injecting the trigger current into main SCR. We measured the I-V characteristics, leakage current analysis and ESD robustness characteristics. The proposed ESD protection circuit was validated using a transmission line pulse (TLP) system. From the experimental results, the proposed ESD protection device has a lower trigger voltage of 5.6 V. Also, the robustness has measured to human body model (HBM) 8 kV and machine model (MM) 600 V. The proposed ESD protection device is designed in 0.35 um Bipolar-CMOS-DMOS (BCD) technologies.

This paper is intended to recognize and track objects on real time basis under the embedded environment. Speed and rate of recognition have been improved by strong directional SURF and optical flow, but its speed is not fast enough for the embedded system. In this paper, recognition and tracking objects by integration of ORB and optical flow with a parallelization using OpenMP are implemented. The result shows an improved processing speed.

This paper proposes the Low-Dropout regulator including the "load current sensing circuit". The load current sensing circuit senses the change of the load current and then reduces the ripple of the output voltage. The load transient response characteristic of the Low-Dropout regulator is improved by this method. And this paper uses a body driven technique to enhance the current driving capability for pass transistor. The proposed circuit is simulated by HSPICE with a 0.18 μm BCD process parameter. In addition, this paper enhances the reliability of IC by equipping the P-substrate triggered SCR type ESD protection device.
