SCR based ESD Protection circuit with additional NPN path using skhynix 0.18um process
ESD protection circuit with SK Hynix 0.18um BCD process for power clamp. The circuit has effective ESD performance by using SCR based Device. Also, the circuit has latch-up immunity as well as small area. The Electrical characteristics of ESD protection circuit are verified by using TLP system and ESD simulator (ESD pu..
LIN(Local Interconnect Network) Controller with AMBA APB Interface
LIN (local interconnect network) is a standard low-speed serial communication protocol, and it was developed as an efficient sub-bus for automotive electronic modules. LIN controller was implemented in Verilog HDL, based on LIN ver. 2.2A. The implemented LIN controller was verified in FPGA, and it can be supplied as a..
CAN(Controller Area Network) Controller with AMBA APB Interface
CAN (Controller Area network) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each others’ applications without a host computer. CAN controller was implemented in Verilog HDL, based on CAN ver. 2.0A. The implemented CAN controller was verified in FPGA, and it can be..
DC-DC Buck Converter Using Analog Coarse-Fine Self-Tracking Zero-Current Detection Scheme
This paper proposes a DC-DC buck converter using an analog coarse-fine self-tracking zero-current detection (AST-ZCD) scheme. The AST-ZCD detects the zero-current by measuring the voltage level across a freewheeling transistor. It adjusts the nMOS turn-off time using an amplifier, capacitors, and current sources instea..
Area-Efficient Bidirectional Shift-Register Using Bidirectional Pulsed-Latches
The proposed bidirectional shift-register reduces the area and power consumption by replacing master-slave flip-flops and 2-to-1 multiplexers with the proposed bidirectional pulsed-latches and non-overlap delayed pulsed clock signals, and by using sub shift-registers and extra temporary storage latches.
