We have designed and fabricated a fully-integrated CMOS-based lab-on-a-chip electronics platform to investigate the electrical characteristics of novel nanoelectronic devices. In contrast with previous work which requires the use of external equipment, therefore limiting the range of possible measurements due to parasitic capacitance and inductance, we embed the nanostructures on an integrated circuit produced with a mature 180-nm CMOS process. The test platform includes modules for measuring I-V curves with a driven current range from 100 pA to 100 ?A, and a measured voltage in the 0-1.5 V range. Propagation delay measurement modules as fine as 7 ps are also included. Inputs-outputs and test configurations are controlled using a standard IEEE 1149.1 JTAG scan chain.
