A digital CMOS DNA chip

— A fully electronic medium density DNA micro array is presented using a CMOS process extended by gold electrodes. The chip provides 128 sensor sites, in-sensor site current-mode A/D conversion, peripheral circuitry including bandgap and current references, D/A-converters to provide electrode bias voltages, calibration circuitry, and a 6 pin interface for power supply and serial digital data transfer.
