    A Low-Loss Built-In Current Sensor (1999)
    Springer
    Journal of electronic testing 14 (1999), S. 39-48 
    Details
    ISSN: 1573-0727
    Keywords: Built-in current sensor ; IDDQ testing ; low-voltage LSIs ; multiple power supplies
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology
    Notes: Abstract This paper presents a novel built-in current sensor that uses two additional power supply voltages besides the system power supply voltage, and that is constructed by using a current mirror circuit to pick up an abnormal IDDQ. It is activated only by an abnormal quiescent power supply current and minimizes the voltage drop at the terminal of the circuit under test. Simulation results showed that it could detect 16-μA IDDQ against 0.03-V voltage drop at 3.3-V VDD and that it reduced performance degradation in the circuit under test. It is therefore suitable for testing low-voltage integrated circuits. Moreover, we verified the behavior of the sensor circuit implemented on the board by using discrete devices. Experimental results showed that the real circuit of the sensor functioned properly.

    Mass spectra of π-cyclopentadienyl-diene cobalt complexes (1970)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 3 (1970), S. 23-29 
    Details
    ISSN: 0030-493X
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: Many reports on the mass spectra of organotransition-metal complexes have appeared in recent years,1 whilst there have only been a few reports on the mass spectra of transition metal olefin complexes, some metal carbonyl olefin complexes234 and π-cyclooctenyl-π-cyclooctadienyl cobalt.5 Recently fragmentation paths of π-cyclopentadienyl-cyclooctadiene rhodium were elucidated by King.6 The present authors found metastable ions in the mass spectra of π-cyclopentadienyl-diene cobalt complexes as well as in the mass spectra of π-cyclopentadienyl-diene rhodium complexes.7.In the present paper the authors wish to report the mass spectra of several π-cyclopentadienyl diene cobalt complexes.
