Abstract
A CMOS-integrated electrochemical biochip for
high-performance molecular testing is presented. The system
includes an array of 32 × 32 three-electrode voltammetry pix-
els and on-chip temperature control between 25 and 95
◦C.
Each 100 μm × 100 μm pixel includes a CMOS-compatible and
chemo-stable amorphous carbon electrode transducer connected
to in-pixel current detection circuitry with 280 fA rms
input-referred noise (0.1–20 Hz bandwidth) and 93 dB dynamic
range (DR). Array-based DNA detecti
