Optimized RC timing technique for accurate measurement of minute capacitance changes
This paper presents a technique for accurate measurement of small capacitive changes. This is based on selecting the most linear part of the curve obtained by charging the capacitor undergoing changes through a known resistor value. This measurement is part of the design of a system for measuri...

| description | This paper presents a technique for accurate
measurement of small capacitive changes. This is based on
selecting the most linear part of the curve obtained by charging
the capacitor undergoing changes through a known resistor
value. This measurement is part of the design of a system for
measuring blood glucose content non-invasively. The
technique is based on measuring ultra-low low glucose levels
in the blood as capacitive changes converted into RC timing
constant optimized using a circuit set to trigger at an
appropriate time activating a counter. The measured data is
captured instant later, selecting the most linear part of the
charging curve. The results so obtained are compared with the
ones obtained through RC-timing standard procedure. The
technique reported is with a remarkable low error of about
2.25% as against 11.78% by the standard RC-timing
technique. |
