From Smartphones to Diagnostics: Low Cost Electronics for Programmable Digital Microfluidics and Sensing
نویسندگان
چکیده
We are developing all-electronic sensing and diagnostic platforms based on low-cost electronics as found in smartphones. Our concept is a system that combines digital microfluidics (DMF), based on Electro Wetting on Dielectric (EWOD) with direct electrical readout of assay chemistry using simple transistors. A programmable DMF technology has thousands of electrodes, each of which contains sensors to measure droplet characteristics. These devices are made using Thin Film Transistor (TFT) technology. The same approach is used to make Si nanoribbon sensors that enable direct electrical readout of assays. The system enables many complex assays to be pre-programmed and performed in parallel.

FPGA Implementation of a Hammerstein Based Digital Predistorter for Linearizing RF Power Amplifiers with Memory Effects
Power amplifiers (PAs) are inherently nonlinear elements and digital predistortion is a highly cost-effective approach to linearize them. Although most existing architectures assume that the PA has a memoryless nonlinearity, memory effects of the PAs in many applications ,such as wideband code-division multiple access (WCDMA) or orthogonal frequency-division multiplexing (OFDM), can no longer b...
