Abstract
A device for measuring the glucose level in living tissue has electrodes () for being brought into contact with the specimen and a voltage-controlled oscillator () as a signal source for generating an AC voltage in a given frequency range. The AC voltage is applied to the electrodes (). A voltage over the electrodes is fed to a processing circuitry (), which converts it to the glucose level using calibration data. The voltage-controlled oscillator () has a symmetric design with adjustable gain for generating signals in a large frequency range with low distortions at a low supply voltage. The processing circuit comprises a simple rectifier network with software-based correction. The electrodes () are of asymmetric design and optimized for biological compatibility.
