A fully integrated 10Ã10 electrochemical impedance spectroscopy array is designed for label-free biomolecular detection applications. Each biosensor pixel includes an on-chip bio-functionalized electrode and a direct-conversion receiver capable of measuring complex admittance levels as low as 10·¿¿-1 with a dynamic range larger than 90 dB in a 10 Hz-to-50 MHz frequency range.
