Therefore, the patients will get more comfortable attention by bio-medical SOC chip.e plan to integrate wireless communication, electrical sensor, and software by semiconductor industry and information technology to achieve low-cost, long-tern, small and reliable medical sensors. We design a SOC chip that has the ability of wireless data transmitting and receiving, controllable behavior, and sensing. This SOC includes an ASIC microcontroller, two amplifiers to enlarge different type of signals, a wireless receiver for receiving command, a wireless transmitter for transmitting data, an analog-to-digital converter (ADC) to convert analog signal to digital, two regulators for saving power, and a 4-to-1 multiplex for choosing how many signal passes. All of them are integrated in one single SOC chip. Sensors for detecting biological signal are placed externally.誌謝 i文摘要 iiiBSTRACT vONTENTS viiIST OF FIGURES ixIST OF TABLES xihapter 1 Introduction 1.1 Motivation 1.2 Thesis Organization 4.3 References 5hapter 2 Mixed-signal Circuit Design 6.1 Introduction 6.2 Mixed-signal Circuit Design Flow 8.3 Digital Circuit Design Flow 10.3.1 RTL Design Guide [2.2] 12.3.2 Synthesis 15.3.3 Design for Test 18.3.4 Place & Route 19.4 Digital Signal Processing Architecture Design 22.4.1 Pipelining and Parallel Processing [2.4] 22.4.2 Retiming [2.4] 24.4.3 Other Low Power Designs for Digital Circuits 25.5 References 27hapter 3 Wireless Sensor Node SOC with ASIC Microcontroller 28.1 Introduction 28.2 System on Chip (SOC) Overview 30.2.1 Wireless Sensor Network Introduction [3.1] [3.2] 30.2.2 The Architecture of SOC [3.3] [3.4] [3.5] 32.3 An ASIC Microcontroller Feature & Architecture 34.3.1 Controller Operation 36.3.2 Data Packet Format & Low Power Design 39.3.3 Universal Asynchronous Receiver/Transmitter [3.6] 42.3.4 Core 44.4 Analog & RF circuits [3.7] 47.4.1 ASK Transmitter 47.4.2 OOK Receiver 49.4.3 Instrument Amplifier 50.4.4 Successive Approximation ADC 52.4.5 Trans-Impedance Amplifier 54.4.6 Voltage Regulator 55.4.7 Analog 4-to-1 Multiplexer 57.5 Measurement for the ASIC Microcontroller 59.5.1 PCB Design for Testing 60.5.2 Measurement Setup and Result 62.5.3 Specification Summary 65.6 References 66hapter 4 Analog FFT Processors for OFDM Receivers 67.1 Introduction 67.1.1 The Basic Introduction of OFDM [4.1] [4.2] 67.1.2 The Typical OFDM Communication Transceiver System Model [4.2] 69.1.3 The Analog OFDM Communication Transceiver System Model [4.3] 71.2 FFT Algorithm & the Basic Circuit [4.3] [4.4] 73.2.1 The Introduction of FFT Algorithm 73.2.2 The Basic Circuits of the Analog FFT 75.3 A Radix-2, Analog 8-FFT Processor Implementation 77.3.1 Input Interface 77.3.2 Implementation of the Analog FFT Processor 78.3.3 The Whole Analog FFT Circuit 80.4 Simulation Result for an Analog FFT processor 82.4.1 The Tran-conductance Circuit 82.4.2 The Cascode Current Mirror 83.4.3 The Whole Analog FFT Circuit 84.5 References 85hapter 5 Conclusion 86ppendix A Related Patent Collection and Analysis 882814370 bytesapplication/pdfen-US微控制器中央處理單元系統單晶片無線感測網路無線生醫量測MicrocontrollerCentral Processing UnitSystem on a ChipWireless Sensor NetworkWireless Bio-medical Sensorthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/189249/1/ntu-98-R96943100-1.pdf
