A RISC-V based medical implantable SOC for high voltage a current tissue stimulus
Arnaud Maceira, Alfredo; Gak Szollosy, Joel; García Ramírez, Ronny; Rimolo Donadio, Renato; Miguez De Mori, Matías Rafael; Puyol, Rafael; Solera Bolanos, Edgar; Castro González, Reinaldo; Molina Robles, Roberto; Chacón Rodríguez, Alfonso (IEEE, 2020)A RISC-V based System on Chip (SoC) for high voltage and current tissue stimulus, targeting implantable medical devices, is presented. The circuit is designed in a 0.18μm HV-CMOS process, including the RISC-V 32RVI based ... -
Integrated programmable current source for implantable medical devices
Rimolo Donadio, Renato; Chacón Rodríguez, Alfonso; Gak Szollosy, Joel; García Ramírez, Ronny; Miguez de Mori, Matías Rafael; Arnaud Maceira, Alfredo; Hardy, D.; Agis, L.; Nakasone Lanza, Kenji Sebastián (IEEE, 2020)In this work, the design and implementation of a 25mA (max), 8 bits integrated programmable current source for implantable medical devices is presented. The proposed circuit includes a six-bits trimming mechanism to balance ... -
