A CMOS General-Purpose Sampled-Data Analog Processing Element

چکیده
This brief presents the architecture and implementation of an analog processor, which in a way akin to a digital microprocessor, embodies a physical model of the universal Turing machine. The analog microprocessor (A P) executes software programs, while nevertheless operating on analog sampled data values. This enables the design of mixed-mode systems which retain the speed/area/power advantages of the analog signal processing paradigm, while being fully programmable general-purpose systems. A proof-of-concept integrated circuit has been implemented in 0.8m CMOS technology, using switched-current techniques. Experimental results from fabricated chips are presented and examples of the application of the A P’s in image processing are given.

متن کاملA Multichannel Recording Frontend for MEA
Glass-substrate Multi-electrode Arrays (MEAs) have become a valuable tool in neurophysiological research and drug screening. A typical setup for MEA recording is based on discrete-element preamplifiers located close to the MEA device and a multi-wire cable that conducts the pre-amplified analog signals to a data acquisition card. With the increase in the number of MEA sensing sites, this approa...
