Abstract Various emerging technologies provide the potential for advancing the development of hardware security concepts. A review of some emerging technologies includes spintronics, memristors, carbon nanotubes and related transistors, nanowires and related transistors, as well as 3D and 2.5D integration. These emerging devices share some interesting characteristics that are difficult to achieve with traditional CMOS … Read more
Click the blue WeChat name below the title to quickly follow With the continuous development of process nodes (now commonly at 28nm, 22nm, 16nm, 14nm, and even some at 7nm), the performance demands of chips are increasing, and their scale is growing larger. Digital IC design engineers are becoming increasingly concerned about chip power consumption, … Read more
Low Power Design Techniques: Power Gating and Isolation Cells Previously, we discussed the Multi Vdd technology and Power Gating technology in low power design: Low Power Design Techniques – Multi VDD Low Power Design Techniques – Power/Ground Gating – Power Switching Cell In the introduction of Power Gating, we detailed the Power Switching Cell; here … Read more
In the early stages of IC design, the main parameters of concern were performance (timing) and area. EDA tools minimized area while meeting performance requirements. At this time, power consumption was not a major concern. Because CMOS technology exhibits relatively low power consumption at lower clock frequencies, leakage current can be negligible. However, as transistor … Read more
Low power design is an indispensable topic in modern chip design. After all, no one wants their phone or other electronic devices to require frequent charging. Especially for small products, many people cannot accept the need for an external power supply to function normally. Since the inception of electronic devices, there has been a continuous … Read more
Power Consumption in CMOS Circuits is Divided into Two Parts: Static Power Consumption and Dynamic Power Consumption; Static power consumption is caused by leakage current; dynamic power consumption is divided into switching power and short-circuit power. Switching power is the power consumed during the transition from 0 to 1, while short-circuit power occurs when both … Read more
Common faults and solutions for industrial computers: 21 items: 1. Power on the computer but it does not respond: 1. Check if the power outlet has electricity and is properly connected to the computer; 2. Check if the computer power supply is functioning normally (check if the power supply fan spins after powering on) and … Read more
The ELF 1 and ELF 1S development boards are compatible with the OV5640 camera, which integrates a CMOS image sensor. As a 5-megapixel camera, it supports image output with a maximum resolution of 2592×1944 (QSXGA) and a frame rate of up to 15fps. It also supports high-speed VGA (640×480) image capture at 90fps, demonstrating excellent … Read more
CIS: The Soul and Value Core of CMOS Camera Modules, Domestic Substitution Enters Deep Waters. Functionally, CIS is currently the most mainstream image sensor that can capture photons and convert them into electrical signals, serving as the core component for imaging in CMOS camera modules; in terms of value, CIS accounts for approximately 52% of … Read more
