CONCLUSIONS
Low cost & reusable “biological” oscillator for Cell
Culture growing measurements.
 Amplitude and frequency to characterize occupation.
 AGC for better noise inmunity
 Frequency and AGC control voltage (Vg) to extract Fill
Factor (ff) parameter.
 Potential fields of application: medicine and biology
