Using silicon-integrated circuit technology, we have fabricated a flexible multi-electrode array and used it for measuring evoked potentials at the surface of the ferret primary auditory cortex (AI). Traditionally, maps of cortical activity are recorded from numerous sequential penetrations with a single electrode. A common problem with this approach is(More)
Title of dissertation: LOW FREQUENCY NOISE IN CMOS TRANSISTORS Anshu Sarje, Doctor of Philosophy, 2013 Dissertation directed by: Professor Martin Peckerar Department of Electrical and Computer Engineering The minimum measurable signal strength of an electronic system is limited by noise. With the advent of very large scale integrated (VLSI) systems, low(More)
Motivated by the need for highly efficient far-IR Fabry-Perot étalons for airborne and space astronomy, we have developed a high-yield photolithographic technique for producing low-loss metal-mesh reflectors. We describe the production technique and report on the mesh flatness and uniformity. Optical measurements of meshes produced by this technique show(More)
A low-noise readout array is proposed for use with high capacitance detectors. The readout array is composed of a pre-amplifier/amplifier chain. The signal processing chain is designed for use with CdZnTe gamma ray detectors employed by NASA for radiation detection. This approach employs correlated double sampling and capacitive matching to increase the(More)
