Implantable biotelemetry systems are indispensable tools not only in animal research but also in clinical medicine as such systems enable the acquisition of otherwise unavailable physiological data. This paper describes the manufacture of custom CMOS LSI to implement an implantable biotelemetry system. The internal circuits of this system are fabricated on a single silicon chip with a size of 4 x 5 mm. This IC is designed and manufactured not only to achieve as small size and low power dissipation as possible, but also to have multiple functions. Its main functions are to select one of implanted sensors and to accomplish On-Off power switching of an implanted battery by receiving appropriate control signals and command signals from an external circuit. This system, used together with appropriate sensors, is expected to be capable of measuring and transmitting such significant parameters as pressure, pH and temperature.
可植入生物遥测系统不仅在动物研究中，而且在临床医学中都是不可或缺的工具，因为此类系统能够获取其他方式无法获得的生理数据。本文描述了用于实现可植入生物遥测系统的定制CMOS大规模集成电路的制造。该系统的内部电路制作在一个尺寸为4×5毫米的单晶硅芯片上。此集成电路的设计和制造不仅是为了尽可能实现小尺寸和低功耗，而且还具备多种功能。其主要功能是通过接收来自外部电路的适当控制信号和命令信号，选择一个植入式传感器，并完成植入式电池的通断电源切换。该系统与适当的传感器一起使用，有望能够测量和传输诸如压力、pH值和温度等重要参数。
