A novel ultra-high compliance, low power, very accurate and high output impedance current output stage (COS) with extremely high output current drive capability is proposed in this paper. The principle of operation of this unique structure is discussed, its most important formulas are derived and its outstanding performance is verified by HSPICE simulation in TSMC 0.18µm CMOS, BSIM3, and Level4...

background: the possible role of cochlear function in tinnitus generation is still a matter of debate. to assess the role of outer hair cell dysfunction in tinnitus and its possible relationship with ultra-high frequency (uhf) hearing sensitivity, transient evoked otoacoustic emissions (teoae) and uhf hearing thresholds were investigated in normal hearing individuals with and without tinnitus. ...

the austenitic stainless steel (ss) has been used as a material for  building  ultra  high  vacuum  (uhv)  chamber.  recently significant  efforts  have  been  concerned  a  comparing  the standard  cleaned  for  ultra  high  vacuum,  passivity  stainless. in  this work austenitic  nanocomposites were  synthesize by sol-  gel method. the morphologies  and  topographies  of  the samples  have  b...

In this paper a novel ultra-high compliance, low power, very accurate and high output impedance current mirror/source is proposed. Deliberately composed elements and a good combination (for a mutual auto control action) of negative and positive feedbacks in the proposed circuit made it unique in gathering ultra-high compliances, high output impedance and high accuracy ever demanded merits. The ...

In this paper we propose a tick time model for dealer quote interactions using ultra-high-frequency data. We include duration functions to measure the time dependence of volatility as well as information. In order to asses price discovery we define several measures in tick time. These measures can be aggregated to calender time and we define a comparative measure to Hasbrouck (1995) information...

in this study an ultra-broad band, low-power, and high-gain cmos distributed amplifier (cmos-da) utilizing a new gain-cell based on the inductively peaking cascaded structure is presented. it is created bycascading of inductively coupled common-source (cs) stage and regulated cascode configuration (rgc).the proposed three-stage da is simulated in 0.13 μm cmos process. it achieves flat and high ...

there are described nanocomposites based on ultra high molecular weight polyethylene and graphite nanoplates prepared by in-situ polymerization method. it is carried out a comprehensive study of electric properties of these composites, including direct current (dc) and alternating current (ac) properties. there is explored dependence of the conductivity and dielectric permeability on filler con...
