As the first and important component in the delta-sigma modulator, the input integrator should be considered since it affected directly on the input signal, this integrator dominates the total performance of the sigma-delta modulator. ![]() INPUT CBSC INTEGRATOR FOR DELTA-SIGMA MODULATOR This type of integrator is suitable for using in delta-sigma modulator (fig.1). Section IV is about logic part of CBSC integrator that produces control signals and in section V we explain an example in order to more clearance. Also, stability issues are removed with absence of the OPAMP.in this paper we present the required circuits and equations for designing a CBSC integrator in section III. This makes it possible to also take advantage of the increased speed in modern technologies to create high-speed comparators. Instead of forcing the input nodes to the ground, the charge transfer process is performed by current sources, while the virtual ground condition is detected by a comparator instead of being forced by OPAMPs. CBSC has benefits which coincide well with technology scaling. This again causes new problems such as high power consumption and stability issues. It is possible to compensate by using cascod devices, cascading several stages, compensation techniques and so on. With OPAMP based circuits, the accuracy of the circuit is very dependent of the open loop gain of the OPAMPs.

These tools allow you to compare two files of any type, including PDFs, and highlight any differences between them.Electrical and Electronics Engineering: An International Journal (ELELIJ) Vol 4, No 1, February 2015 DOI : 10.14810/elelij.2015.4108 87 A DESIGN GUIDE FOR C OMPARATOR -B ASED S WITCHED -C APACITOR I NTEGRATOR Sadegh Biabanifard 1, Toktam Aghaee 2 and Shahrouz Asadi 2 1 Microelectronic Lab, Shahid Beheshti University, G. Use a file comparison tool: If you don't have access to a PDF comparison tool, you can also try using a file comparison tool, such as WinMerge or Beyond Compare. These tools typically highlight any differences between the two files and allow you to download the compared PDF. Use an online comparison tool: There are several online tools available that allow you to upload two PDF files and compare them for free, such as Smallpdf, Sejda, and Draftable. These tools allow you to compare two PDF files side-by-side and highlight any differences between them, such as changes in text, images, or formatting. Use a dedicated PDF comparison tool: There are several tools available that are specifically designed to compare PDF files, such as DiffPDF, Adobe Acrobat Pro, and Compare Suite. There are several ways to compare two PDF files, depending on your needs and the tools you have available. ![]()
