Novel Mixed Domain VLSI Signal Processing Circuits for High Performance, Low Power and Area Penalty SOC Signal Processing

The ever-growing field of VLSI has witnessed a lot of recent developments and changes over the course of time. VLSI began in the 1970s when MOS integrated circuit chips were widely adopted, enabling complex semiconductor and telecommunication technologies to be developed. System-on-a-chip(SOC) circuit technologies have made their presence felt more than ever and area unit primarily driven by the short growth of worldwide markets for mobile computing, large scaled industries, inter and intra communication as well as physical science, targeted at higher performances and lower cost that’s featured by the increasing level of integration with complete system being integrated on one chip that has analog, digital, and RF circuits.

There are a pair of trends ascertained as regards to the VLSI SOC signal process system (SOCSP) which are observed in this paper- increasing analog circuit effects in high performance digital circuits that require analog circuit solutions the rise of contents of analog signal process (ASP) being replaced by digital signal process (DSP). As a result of this, we tend to expect to look at the continuing shifting of the ASP and DSP circuit boundary that finally ends up in innovated VLSI SOCSP circuit solutions mistreatment every VLSI ASP and DSP circuit techniques for higher system performance and potency at a reduced price. Additionally, the analog nature of front-end circuits in SOCSP applications conjointly do find themselves in utilizing and needing dedicated ASP operations.

The paper has a certain pattern and train of thought when it comes to ASP and DSP that can be observed by the reader: first up we have a review of basic VLSI techniques in ASP and DSP. We then move onto their corresponding circuits and follow them up with some examples to learn that a novel VLSI circuit technique providing higher computation potency, performance and lower power/area penalty and PVT sensitivity is conferred. Such technique provides a good method for implementing VLSI signal processing operation for varied SOC applications.
