This paper presents the first voltage-calibrated CMOS time-domain smart temperature sensor to reduce the cost of mass production. A digitally adjustable relaxation oscillator designed as the temperature sensor vibrates between CMOS-based CTAT, PTAT voltage references with mutual curvature compensation to generate linear temperature-dependent output pulses. Voltage instead of temperature calibration...
The arylthioether diazonium ion is coupled with imidazole to synthesize tridentate imidazolylazothioether-based NN′S ligands. The reaction of CuCl 2 ·2H 2 O with NN′S ligands has synthesized penta-coordinated Cu(NN′S)Cl 2 compounds. The structure has been confirmed by an X-ray diffraction study in one case and also by other spectroscopic and magnetic properties. α-Diimine (N,N)...
The reaction of green vitriol (FeSO 4 ,7H 2 O) with 1-alkyl-2-(arylazo)imidazoles [RaaiR′ where R=H (a), Me (b); R′=Me (1/3/5), Et (2/4/6)] and NH 4 SCN in 1:2:2 mole proportion affords mononuclear bis-chelated [Fe(RaaiR′) 2 (SCN) 2 ] (3,4) complexes. Reaction of NiSO 4 ·6H 2 O with 1-alkyl-2(arylazo)imidazole and ammonium thiocyanate (1:2:2...
