The reliable operation of SRAM in presence of process variation in sub-100nm devices is largely influenced by periphery circuits, like sense amplifiers, demanding more robust solutions. A new differential sense amplifier for use in standard 6-T SRAM based on gated-diode is proposed and designed. For comparison, three other latch-based sense amplifiers are also designed in 45nm technology. The b...

A 90-nm wideband (1500-1590nm) optical amplifier consisting of a dispersion-compensated-fiber-based Raman fiber amplifier and a semiconductor optical amplifier with gain clamping and dispersion compensation is demonstrated for wide bandwidth amplification with gain flatness as well as dispersion compensation. 10Gb/s DWDM transmission over 100km conventional single-mode fiber link with low biter...

To combine the benefits and compensate for the drawbacks of different optical amplifier types, a hybrid amplifier can be composed. The authors consider two most frequently used hybrid amplifiers that can provide better performance: a semiconductor optical amplifier (SOA), and an erbium doped fiber amplifier (EDFA), both in combination with a distributed Raman amplifier (DRA). To compare perform...

This paper presents a design of the transimpedance amplifier using 0.35μm CMOS technology. In the proposed transimpedance amplifier, feedback resistor RF of conventional transimpedance amplifier has been replaced by NMOS transistor as an active feedback resistor. This circuit operates at 3.3V power supply voltage and for a photocurrent of 0.5μA.The proposed transimpedance amplifier having low n...

Presented is a 0.9 V rail-to-rail constant gm CMOS amplifier input stage consisting of complementary differential pairs and a gm control circuit. The gm control circuit eliminates the gm dead zone, which occurs in the conventional rail-to-rail amplifier with ultra-low supply voltages. The proposed amplifier input stage has a constant gm that varies by +2.3% for rail-to-rail input common-mode le...

Integration of distributed energy resources, such as photovoltaic solar (PV), introduces new opportunities to establish local market frameworks improve renewable utilisation in residential sectors. Such peer-to-peer (P2P) trading refers a structure where customers (and prosumers) interact share excess PV generation enhance the individual and community social welfare. In this work, day-ahead con...

We propose and analyze a new type of optical amplifier that is formed by addition of gain in the periodic cladding of a transverse Bragg resonance waveguide [Opt. Lett. 27, 936 (2002)]. Using the coupled-wave formalism, we calculate the mode profiles, the exponential gain constant, and, for comparison, the gain enhancement compared with those of conventional semiconductor optical amplifiers. In...

Background: Documents constructed according to the HL7 Clinical Document Architecture (CDA) need to be reviewed, edited and approved by an author, who is usually a clinician. The CDA specification does not require any particular editing tool to be used in creating CDAs. The tools used to edit CDAs have typically been specific to a particular profile of CDA, and even to the application using tha...
