Abstract :
A 8-channel dedicated microprocessor for externally powered implantable pain control stimulator is presented. It is designed with 8 channels to deliver the stimuli: any subset out of 8 channels can be started or stopped simultaneously. Arbitrary current waveforms can be generated through appropriate programming which can be achieved by an algorithm serially transmitted transdermally. The microprocessor can be configured as biphasic or monophasic or mix operation mode. Particularly, the charge balanced biphasic pulses are easily generated. The design is accomplished with Verilog HDL language description at RTL level. The resulting schematic or netlist is then automatically placed and routed by Preview Cell Ensemble with the 1.5 micron Mitel process
