Layout Dependent Matching Analysis of CMOS Circuits
نویسندگان
چکیده
Layout has strong influence on matching properties of a circuit. Current matching models, which characterize both local random non-uniformities and global systematic non-uniformities stochastically, are not adequate for the matching analysis taking the effect of layout realization into account. In order to consider topological information of layout into matching analysis, we propose a matching model which treats the random and systematic components separately. Also, we characterize the micro-loading effect, which modulates fabricated line-width according to the local density of layout patterns, into matching analysis. With these two techniques, we can perform matching analysis of CMOS circuits taking layout information into account. key words: CMOS, matching, micro-loading-effect, fluctuation

A Broadband Low Power CMOS LNA for 3.1–10.6 GHz UWB Receivers
A new approach for designing an ultra wideband (UWB) CMOS low noise amplifier (LNA) is presented. The aim of this design is to achieve a low noise figure, reasonable power gain and low power consumption in 3.1-10.6 GHz. Also, the figure of merit (FOM) is significantly improved at 180nm technology compared to the other state-of-the-art designs. Improved π-network and T-network are used to obt...
متن کاملExplicit Characterization of Bandgap References Table of Contents
Stable and precision voltage references are an integral part of many analog and mixed-signal integrated circuits. Bandgap references have been widely used for precision on-chip voltage sources in both bipolar and CMOS processes. Conspicuously absent in the literature are explicit relationships between the output voltage and temperature of bandgap references. Temperature characteristics of bipol...

This work studies the effects of dynamic threshold design techniques on the speed and power of digital circuits. A new dynamic threshold transistor structure has been proposed to improve performances of digital circuits. The proposed switched-capacitor dynamic threshold PMOS (SC-DTPMOS) scheme employs a capacitor along with an NMOS switch in order to effectively reduce the threshold voltage of ...
متن کاملSystem Design Considerations When Using Cypress CMOS Circuits
To achieve maximum performance when using Cypress CMOS ICs, pay attention to the placement of the components on the printed circuit board (PCB); the routing of the metal traces that interconnect the components; the layout and decoupling of the power distribution system on the PCB; and perhaps most important of all, the impedance matching of some traces between the source and the loads. The latt...
متن کاملFault Tolerant Reversible QCA Design using TMR and Fault Detecting by a Comparator Circuit
Quantum-dot Cellular Automata (QCA) is an emerging and promising technology that provides significant improvements over CMOS. Recently QCA has been advocated as an applicant for implementing reversible circuits. However QCA, like other Nanotechnologies, suffers from a high fault rate. The main purpose of this paper is to develop a fault tolerant model of QCA circuits by redundancy in hardware a...
