Analog-to-digital converters (ADCs) are chief design blocks in todays microelectronic digital communication systems. In simple word, ADC acts as a bridge between the analog and digital worlds. With time the advancement in CMOS technology, more & more signal processing functions are incorporated in...
根据ADC的使用方式,选择电压基准电路的使用方式,可以在保证性能的前提下,兼具电源电压低、功耗低、应用灵活的优点。 1 SAR ADC基本原理 图1所示为电荷型SAR ADC的基本架构[1]。SAR ADC的基本结构包含一个比较器、一个数字模拟转换器(Digital-Analog Convertor,DAC)和一个逐次逼近控制器(SAR Logic)。DAC采用电荷按...
In addition to the high computing power RISC-V CPU, the HPM6200 product also integrates a series of high-performance peripherals and external storage. Further, the HPM6200 series also provides an enhanced PWM control system and a programmable logic array PLA for complex signal generation. Integra...

Logic Expression A = (Mode Condition 1 (OR或AND或XOR或NAND)Mode Condition 2 ); 模式规则(ModeRules) 模式规则指的是根据上述逻辑表达式的结果(TRUE or FALSE)来执行相应的Action List。也就意味着模式规则是为了实现逻辑表达式与相应Action List 的Mapping关系。 为了对模式仲裁过程中的三大构件(模式请求来源、...
softwareclusterdesign需要和MachineDesign相关联 softwarecluster需要和softwarecluster design相关联 Function Group State:功能组状态,是指一个功能集群(Function Group)的整体状态,它反映了该功能集群内部所有进程或自适应应用程序的执行状态的综合情况。功能组状态由状态管理(State Management)模块控制和监视。
This analog-to-digital converter uses Successive Approximation Register (SAR) architecture to achieve 12-bit resolution. The IP includes a core internal SAR ADC, 8-1 MUX and touch screen drivers. The internal SAR ADC includes sample/hold circuits, a capacitive DAC, a comparator and logic control...
