技術應用範圍
Technical application scope
 華星科技目前發展之IC設計技術可應用之範圍很
廣，就如原油可變成不同種產品一樣。At present IC of
design technique the development may scope of the application be very broad, like the crude oil
invariably becomes the different product to be the same
 華星科技感興趣或意義的產品領域Is interested or the significance
product domain：
1.健康/醫療/照護The health/medical service/looks after
2.車用Sensor/控制、TPMS、電動車窗Power window
3.工業用 Sensor/控制，如數位錶、壓力錶、板手
Like several tables, pressure gauge, trigger
4.玩具Toy

RFID Introduction 1



RFID=RF + ID
源自空軍敵我識別應用 Air-craft ID App.
RF signals：AM, FM, HF, UHF…
• 有不同的通訊協定(protocols)
• RFID, Zigbee, Bluetooth, Wi-Fi, WMAX, WLAN,
GSM, GPRS, 3G…
7
RFID 特性(characteristic)






有身份辨識碼 (ID)
簡化的RF技術，非用於大資料串的應用(simplified
RF for low bit rate data or information)
作人、事、地、物的事件即時訊息(things Inf.)
無方向性，較易自動化應用( directionless, auto, real
time)
相較於1~2維條碼，資訊較多、較保密性( more
secure and information compare to Bar-code)
作非接觸的隔空量測 ( contactless)

The types of RFID

目前RFID常用的通訊協定有：Protocol

Modulation型式有：
• ISO/IEC
• EPC
• NFC
• ASK
• FSK
• PSK

RFID分類
• 用最簡化的通訊協定作RF訊號的傳送
• 簡單/潔淨的通訊－低RF污染/最美
38
 RFID Technology Issues：
• 讀寫器(Reader) :
• 通訊協定(protocol)
• 天線 (Antenna) --效率與功率及靈敏度低Noise及低EMI/EMC
• Transmitter/Receiver--效率與功率及靈敏度低Noise及低
EMI/EMC
• System control
• 標籤(Tag)：
• 通訊協定(protocol)
• 天線(Antenna )
• 低功耗( Low power)
39

RFID design and Application Issues
• 天線/Reader
• 如何克服干擾是RF天生的問題 ( interference)
• 防碰撞(Anti-collision)
• 因地置宜(environments)
• Low power
• IC
• Package

The trend of RFID
 RFID with M-phone
 RFID with Middle distance RF
communication system
 RFID with Sensing device
 Lower power for human interface
 High power for store or control
