An inexpensive integrated circuit intracranial stimulator

An inexpensive Arduino-based LED stimulator system for vision research.

Light emitting diodes (LEDs) are being used increasingly as light sources in life sciences applications such as in vision research, fluorescence microscopy and in brain-computer interfacing. Here we present an inexpensive but effective visual stimulator based on light emitting diodes (LEDs) and open-source Arduino microcontroller prototyping platform. The main design goal of our system was to u...

An implantable mixed analog/digital neural stimulator circuit

This paper describes a chip for a multichannel neural stimulator for functional electrical stimulation. The chip performs all the signal processing required in an implanted neural stimulator. The power and signal transmission to the stimulator is carried out via an induce -

An Analog Integrated Circuit Design Laboratory

We present the structure of an analog integrated circuit design laboratory to instruct at both, senior undergraduate and entry graduate levels. The teaching material includes: a laboratory manual with analog circuit design theory, pre-laboratory exercises and circuit design specifications; a reference web page with step by step instructions and examples; the use of mathematical tools for automa...

An Approach to Integrated Numericaland Symbolic Circuit

An interface to symbolic circuit analysis has been developed for a SPICE{like circuit simulator in order to integrate numerical simulation with an existing program for symbolic circuit analysis. In eeect, both numerical and symbolic analyses use the same internal representation of circuits which makes the two approaches truly complementary. This integrated simulation capability is used in simul...
