Electrostatic discharge (ESD) is one of the most prevalent threats to the reliability of electronic components. It is an event in which a finite amount of charge is trans- ferred from one object (i.e., human body) to another (i.e., microchip). This process can result in a very high current passing through the microchip within a very short period of time, and, hence, more than 35% of chip damages can be attributed to an ESD-related event. As such, designing on-CHIP ESD structures to protect integrated circuits against the ESD stresses is a high priority in the semiconductor industry.

数字化电源的特点：1.控制智能化它是以数字信号处理器(DSP)或微控制器(MCU)为核心，将数字电源驱动器及PWM控制器作为控制对象而构成的智能化开关电源系统。传统的由微控制器控制的开关电源，一般只是控制电源的启动和关断，并非真正意义的数字电源。2.数模组件组合优化采用“整合数字电源”(Fusion Digital Power)技术，实现了开关电源中模拟组件与数字组件的优化组合。例如，功率级所用的模拟组件MOSFET驱动器，可以很方便地与数字电源控制器相连并实现各种保护及偏置电源管理，而PWM控制器也属于数控模拟芯片。3.集成度高实现了电源系统单片集成化(Power System on Chip)，将大量的分立式元器件整合到一个芯片或一组芯片中。4.控制精度高能充分发挥数字信号处理器及微控制器的优势，使所设计的数字电源达到高技术指标。例如，其脉宽调制(PWM)分辨力可达150ps(10~12s)的水平，这是传统开关电源所望尘莫及的。数字电源还能实现多相位控制、非线性控制、负载均流以及故障预测等功能，为研制绿色节能型开关电源提供了便利条件。5.模块化程度高数字电源模块化程度高，各模块之间可以方便地实现有机融合，便于构成分布式数字电源系统，提高电源系统的可靠性。

数字示波器功能强大,使用方便,但是价格相对昂贵。本文以Ti的MSP430F5529为主控器,以Altera公司的EP2C5T144C8 FPGA器件为逻辑控制部件设计数字示波器。模拟信号经程控放大、整形电路后形成方波信号送至FPGA测频,根据频率值选择采用片上及片外高速AD分段采样。FPGA控制片外AD采样并将数据输入到FIFO模块中缓存,由单片机进行频谱分析。测试表明:简易示波器可以实现自动选档、多采样率采样、高精度测频及频谱分析等功能。Digital oscilloscope is powerful and easy to use, but also expensive. The research group designed a low-cost digital oscilloscope, the chip of MSP430F5529 of TI is chosen as the main controller and the device of EP2C5T144C8 of Altera company is used as the logic control unit. Analog signal enter the programmable amplifier circuit, shaping circuit and other pre-processing circuit. The shaped rectangular wave signal is sent to FPGA for measure the frequency. According to the frequency value to select AD on-CHIP or off-chip high-speed AD for sampling. FPGA controls the off-chip AD sampling and buffers AD data by FIFO module. The single chip microcomputer receives the data, and do FFT for spectrum analysis. The test shows that the simple oscilloscope can realize automatic gain selection, sampling at different sampling rates, high precision frequency measurement and spectrum analysis.

The GL823K integrates a high speed 8051 microprocessor and a high efficiency hardware engine for the best data transfer performance between USB and flash card interfaces. Its pin assignment design fits to card sockets to provide easier PCB layout. Inside the chip, it integrates 5V to 3.3V regulator, 3.3V to 1.8V regulator and power MOSFETs and it enables the function of on-CHIP clock source (OCCS) which means no external 12MHz XTAL is needed and that effectively reduces the total BOM cost.
