Soi design analog memory and digital techniques
But a wave of new FD-SOI devices has reminded chip designers how effective body-biasing technology can be, for example, in creating an ultra-low-leakage sleep state for IoT devices. They have been using it in different forms for many years in bulk CMOS technology. More important, as more FD-SOI chips emerge, designers realize that one unique feature of the FD-SOI technology is its ability to use a wide body-bias range to modulate the transistor V T.ĭesigners are familiar with the concept of body biasing. Chip designers have embraced the idea that FD-SOI and FinFETs can play complementary roles. CMOS integration has reached the limit for planar silicon process. Given much tighter cost and power requirements for such devices, semiconductor companies today accept that they need an alternative to FinFETs.
However, since the market began clamoring for ultra-low-power IoT and 5G devices, the industry is singing a different tune.
TECHNOLOGY & ENGINEERING - Electronics - Solid State.Net common resistance extraction is crucial to design reliability.Semiconductors - Design and construction.It is also intended as a general graduate level text to introduce state of the art design principles for SOI circuit design. SOI Design: Analog, Memory and Digital Techniques will be of interest to circuit design engineers. SOI material is considered here in terms of implementation that are promising or have been used elsewhere in circuit development, with historical perspective where appropriate. Static and dynamic logic circuit design has previously been studied in some detail, however, memory design for SOI and analog circuit designs have hitherto been examined only in a piecemeal manner. SOI Design: Analog Memory and Digital Techniques examines some of the basics, but is primarily concerned with circuit related issues. SOI is the process of choice in various RF applications, particularly when digital circuitry is required. Various processes are examined and comparison is made between bulk and SOI circuit design concepts. The design of analog circuits on SOI, in a mixed signal environment, and memory design in an embedded memory application are discussed. Memory and most analog circuits either interface to, or are incorporated within, a digital environment. SOI is suitable for digital, memory and analog designs, although it is not necessarily straightforward to convert circuits developed for bulk processes into SOI. The exploitation of SOI for analog and memory subsystems, meanwhile, has lagged behind digital developments, but is now beginning to attain a level of parity, with circuits that are in some cases improved over their bulk counterparts. The benefits of this technology for digital applications have been clear for many years. SOI offers numerous opportunities and challenges in the design of low-voltage and low-power CMOS circuits for both analog and digital applications. SOI is also used for power integrated circuits, micro-electromechanical systems (MEMS), integrated optics and high temperature applications. IC processes based on SOI are known to reduce susceptibility to radiation, and have been used for many years in high radiation environments. SOI has also proved to be effective in various niche and growing markets. Silicon on insulator (SOI) is a very attractive technology for large volume integrated circuit production and is particularly good for low-voltage, low-power and high-speed digital systems.
