Circuit Simulation for Mixedsigna Analog/digital Circuits Analog/digital Circuits Circuit Simulation for Mixed-signal Analogldigital Circuits

The increasing use of mixed signal circuits with analog and digital circuitry on the same lchip have created a set of demands that traditional circuit simuiators cannot meet very well. We pmsent techniques to efficiently handle the simulation of mixed signal analog/digital circuits, a d SYMPHONY , a fast mixed-signal simulator which embodies them. SYMPHONY combines a fast simulator for digital ...

signal specific successive approximation analog to digital converter

چکیده: در میان انواع متفاوتی از مبدل های آنالوگ به دیجیتال که تا کنون معرفی شده اند، مبدل های آنالوگ به دیجیتال تقاریب متوالی(sar ) به علت سادگی ساختار و همچنین توان مصرفی کم، همواره یکی از پرکاربرد ترین مبدل های آنالوگ به دیحیتال در کاربرد های بایومدیکال بوده اند. به همین دلیل تاکنون روش های متعددی برای کاهش هرچه بیشتر توان مصرفی در این مبدل ها ارائه شده است که در اکثر آنها توجهی به مشخصات سی...

Designing an Integrated All-Optical Analog to Digital Converter

We present the procedure for designing a high speed and low power all-optical analog to digital converter (AO-ADC), by integrating InGaAsP semiconductor optical amplifier (SOA) with InP based photonic crystal (PhC) drop filters. The self-phase modulation in the SOA can shift the frequency of the Gaussian input pulse. The two output PhC based drop filters are designed to appropriately code the f...

Substrate Noise Simulation Techniques for Analog-Digital Mixed LSI Design

Crosstalk from digital to analog circuits can be causative of operation fails in analog-digital mixed LSIs. This paper describes modeling techniques and simulation strategies of the substrate coupling noise. A macroscopic substrate noise model that expresses the noise as a function of logic state transition frequencies among digital blocks is proposed. A simulation system based on the model is ...
