This paper describes a neurostimulation IC for use in advanced closed-loop neurostimulation applications, such as deep brain stimulation (DBS) for treatment and research of neurological disorders including Parkinson's disease. This system senses and filters neural activity with eight pre-amplifiers, a 200 kS/s 8-bit log ADC and digital filters and incorporates 64 programmable current-stimulation channels. The entire device, implemented in 0.18 m CMOS, occupies 2.7 mm 2 and consumes 89 W in normal operation mode and 271 W in configuration mode from a 1.8 V supply.
We describe a 64 channel closed-loop deep brain stimulator IC for use in research and treatment of Parkinson's disease. The system generates programmable stimulation currents and senses and filters neural activity recorded with an 8 channel preamplifier and 200kS/s 8bit logADC. The entire system implemented in 0.18µm CMOS, occupies 2.67mm 2 , and consumes 271µW from a 1.8V supply. In-vivo test data is presented.
