A 43.56mm2 GSM/EDGE baseband processor in 90nm triple-well CMOS has multi-media and mixed-signal extensions, including a 16b HiFi audio front end. The ARM9 core with thin-gate devices reaches 380MHz operation at 470muW/MHz. Frequency and voltage scaling reduce active power in slow mode by 40% and there are nine independent power domains
Abstract In 1997, the US FDA approved a new bulk toxin source (now referred to as current) for the manufacture of botulinum toxin type A (BTX-A). The current BTX-A preparation has a lower neurotoxin complex protein load than the original BTX-A preparation, which may reduce antigenic potential. The present double-masked, multicenter study compared the efficacy and safety of BTX-A (BOTOX) produced from...
AbstractLocomotor movements are programmed in a specialised neuronal network that is localised in the central nervous system and referred to as the central pattern generator (CPG) for locomotion. This CPG can be activated by pharmacological agents such as monoamines. The aim of the present study was to try to activate the CPGs by using cells that are supposed to release serotonin locally. Adult chronic...
An analog VLSI implementation which mimics the early visual processing stages in insects is described. The system is composed of sixty parallel channels of integrated photodetectors and processing elements. It serves as the front end processor for a motion detection chip. The photodetection circuitry includes p-well junction diodes on a 2 mu m CMOS process and a logarithmic compression to increase...
