Accurate Junction Capacitance Modeling for Substrate Crosstalk Calculation
نویسندگان
چکیده
1. Abstract This paper presents a modeling technique to be used in substrate coupling computation of mixed-signal circuits. Substrate crosstalk can negatively impact the performance of analog circuit elements such as mixers or amplifiers and can lead to a total breakdown of circuit parts. In order to forecast substrate-related problems and to analyze its influence EDA-tools are needed that can be applied during layout verification. Depending on the degree of accuracy interfaces between the designed elements and the substrate region have to be modeled. A very important issue is the calculation of junction capacitors. We propose a method that is capable of accurately determining lumped junction capacitors without measurement or device simulation.

A Bus Encoding to Reduce Crosstalk Noise Effect in System on Chip
This paper proposes a new bus coding scheme for reducing the crosstalk in System on chip(soc). As circuit geometries become smaller, wire interconnections become closer together and taller, thus increasing the cross-coupling capacitance between nets. At the same time, parasitic capacitance to the substrate becomes less as interconnections become narrower, and cell delays are reduced as transist...
متن کاملModeling the Effect of Wire Resistance in Deep Submicron Coupled Interconnects for Accurate Crosstalk Based Net Sorting
It is well known that in deep submicron technologies the coupling capacitance between adjacent wires is a critical portion of the total wire capacitance, while at the same time the capacitance between wire and substrate has become the fringing component. High frequency signals travelling across multiple level interconnect structures generate proximity effects, i.e. crosstalk effects, between ad...
