Abstract
Owing to the Population ageing in the world, many countries include Taiwan have become an aged society which is defined by United Nations. How to assist senior citizens’ life will become an important topic in the future. Depending on the advancement of semiconductor manufacturing technology, it has become a major trend presently to implement a small, low-cost and lower-power system-on-a-chip. This thesis achieved a kind of sensor applied to biomedicine in Wireless Sensor Network, which could be supplied the demand for distance medical treatment.e used TSMC 0.35 μm 2P4M CMOS process to achieve a system-on-a-chip used as a sensor node in Wireless Bio-Sensor Network. The chip includes Microcontroller, On/Off Keying receiver, Amplitude-Shift Keying transmitter, Instrument Amplifier, Analog-to-Digital Convertor, Trans-Impedance Amplifier, Analog Multiplexer and Voltage Regulators. The Microcontroller is programmable and compatible with standard 8051 Instruction Set. We use a new and real five-stage pipeline architecture to improve overall system performance.he programmable Microcontroller contains 8-bits data bus and 12 bits address bus, it can execute 111 instructions. It also equips 256 bytes data memory and 4096 bytes program memory, two timers, clock-divider, two Universal Asynchronous Receiver/Transmitter with Cyclic Redundancy Checks, 8 types of interrupt. Maximum clock rate of the microcontroller can achieve 40MHz. Power consumption is 1.135mA when the applied rate is 4MHz in general. Total chip area of the SOC is 3167μm*3396μm.
