穿过完整皮肤发射生理信息的一切由子测量系统的(?)(?)在于需要低功耗工作。为了在特殊的生理系统中减小功耗,提出了一个利用数字遥测数据链的最佳系统——电路——器件方案。(?)助于附加的I~2L模/数频率计数器,低占空度串行数码编码器和射频脉码调制发射芯片,在等幅波多普勒超声流量计中,实现了(?)(?)器功耗减到1/10。实现这个成绩的关键是最佳化的微功耗线性相容I~2L技术,分层外延,不搭接的N~+环和PNP向下的驱动电器使I~2L组件能够实现低功耗而不增加工艺的复杂性。
Everything that emits physiological information across the entire skin by the (?) (?) Of the sub-measurement system requires low-power operation. In order to reduce power consumption in a particular physiological system, an optimal system-circuit-device approach using digital telemetry data link is proposed. (?) To help additional I ~ 2L A / D frequency counter, low duty cycle serial digital encoder and RF pulse code modulation transmitter chip, in the constant amplitude wave Doppler ultrasonic flowmeter to achieve (?) (? ?) Power consumption reduced to 1/10. The key to achieve this result is optimized micro-power linear compatible I ~ 2L technology, layered epitaxy, non-overlapping N ~ + ring and PNP drive down the electrical components to enable I ~ 2L components to achieve low power consumption Without increasing the complexity of the process.
