应用于植入式医疗器械的低功耗控制器设计
Design of Low Power Consumption Controller Applied to Implantable Medical Device
摘要
Abstract
Objective To meet the special requirement of Implantable Medical Device (IMD), this study designed flexible Micro Control Units (MCU) of low-power consumption and high efficiency to achieve optimal use of battery power. Methods Based on the analysis of IMD mainstream technology, the design of MCU based on 0.18 μm CMOS technical standard was optimized by clock gating, power gating, instruction set improvement, DMA optimization for data paths, etc. Results The die area of the designed MCU was 1.4 mm×0.8 mm, and chip memory owned 79.1 K equivalent gates and 6.6 K on-chip memory. Given a 0.9 V power supply, MCU power consumption was 165 μW, and it could be reduced to 42 μW in idle state. Conclusion The designed MCU can be remotely programmed with low power consumption and high efficiency, which makes the IMD more flexible and energy saving to well perform its monitoring or stimulating function during disease surveillance or treatment.关键词
