Definition of capacitance in English:



  • 1Physics
    The ability of a system to store an electric charge.

    ‘The planar spiral wound conductive traces are further preferably suspended over the ground plane of the RF module substrate by micromachining underlying substrate material away to thereby reduce parasitic capacitances.’
    • ‘The slew rate of one or more edge transitions associated with the output signal are controlled using one or more parasitic capacitances associated with the fabrication of two or more cascode connected MOS devices.’
    • ‘Megakaryocyte capacitances were in the range of 64-694 pF, equivalent to 500-5500 platelets.’
    • ‘Disclosed are a capacitor for semiconductor devices capable of increasing storage capacitance and preventing leakage current, and method of manufacturing the same.’
    • ‘The second bipolar waveform allows a measurement of the battery capacitance to be obtained and an evaluation of the charge of the battery to be derived.’
    1. 1.1The ratio of the change in an electric charge in a system to the corresponding change in its electric potential.
      ‘For the lowest noise, you should try to select a PD with maximum shunt resistance and low capacitance.’
      • ‘The metal plates extend substantially vertically through the thicker dielectric material separating the interconnect layers, to provide a relatively high capacitance per unit of surface consumed.’
      • ‘A bilayer electrophysiological setup allowed for measurements of membrane conductance and capacitance.’
      • ‘Each data point represents the average from capacitance measurements of three or four independent planar bilayer samples of the same lipid composition.’
      • ‘In deep trench technology very large aspect ratios (depth versus width of trench) of more than 70: 1 are achieved which allow realisation of sufficient capacitances in spite of smaller process structures.’
