چکیده
INTRODUCTION The complex electronic systems being designed today often require mixed technologies to incorporate the most efficient balance of performance, speed, power, and cost. In order for one technology to communicate with the other, an interface is needed. One of the most common mix of technologies seen today is high speed ECL with the slower, but very popular TTL and CMOS. To make this interface as quick and clean as possible, level translators are used. This applications note will discuss ECL to TTL and TTL to ECL level translators available from Fairchild Semiconductor’s F100K ECL 300 Series product line. Focus will be on Dual Rail Translators (translators which require both ECL and TTL power supplies for normal operation), their differentiating features and possible uses.

CMOS Logic and Current Mode Logic
This chapter describes basic logic circuits. This can be seen as largely background material for applications in later chapters in the design of dividers and phase detectors in frequency synthesizers. The types of logic discussed will be CMOS rail-to-rail logic, CMOS current mode logic (CML), bipolar CML, and bipolar emitter coupled logic (ECL). Note that CML is a general term and applies to bo...
متن کاملThermoeconomic Analysis and Parametric Study of Geothermal and Biomass Source ORC, Dual Fluid and Hybrid Power Plants
In this paper, we have continued doing a research project which had done previously. Three types of power plants include an Organic Rankine Cycle (ORC), a Dual-Fluid-Hybrid (DFH) and a single-fluid hybrid-fueled (HYB); were re-modeled. After model validation, thermodynamic studies and exergy analysis were extended for the defined cases using the first and second laws of thermodynamics. Then the...
متن کاملAn Asynchronous FPGA Based on LEDR/4-Phase-Dual-Rail Hybrid Architecture
This paper presents an asynchronous FPGA that combines 4-phase dual-rail encoding and LEDR (Level-Encoded Dual-Rail) encoding. 4-phase dual-rail encoding is employed to achieve small area and low power for function units, while LEDR encoding is employed to achieve high throughput and low power for the data transfer using programmable interconnection resources. Area-efficient protocol converters...
متن کاملImproving the Security of Dual-Rail Circuits
Dual-rail encoding, return-to-spacer protocol and hazard-free logic can be used to resist differential power analysis attacks by making the power consumption independent of processed data. Standard dual-rail logic uses a protocol with a single spacer, e.g. all-zeroes, which gives rise to power balancing problems. We address these problems by incorporating two spacers; the spacers alternate betw...
متن کاملImproving the security of dual - rail circuits ( revision 2 )
Dual-rail encoding, return-to-spacer protocol and hazard-free logic can be used to resist power analysis attacks by making energy consumed per clock cycle independent of processed data. Standard dual-rail logic uses a protocol with a single spacer, e.g. all-zeroes, which gives rise to energy balancing problems. We address these problems by incorporating two spacers; the spacers alternate betwee...
