NETWORKING LAB PROGRAMS In this paper, we use a wireless sensor network with 100 unknown nodes, which are randomly produced and uniformly distributed in a square region of 5R*5R. Assuming that all nodes are located in the first quadrant, the l

TI公司的ADS1299是8路低噪音同时取样的24位delta-sigma ADC,并内置了可编程增益放大器(PGA),基准电压和振荡器,集成了脑电图(EEG)所需的通用特性.器件具有非常低的输入参考噪音:1.0 μVPP (70-Hz BW),没路的功耗5mW,输入偏置电流300pA,数据速率250SPS到16kSPS,C1.0 μVPP (70-Hz BW),CMMR为-110dB,可编程增益为1, 2, 4, 6, 8, 12或24,单极或双极电源工作,主要用在医疗仪器如EEG和ECG,听

The AGC is a smart programmable gain amplifier (PGA). The amplifier gain is adjusted based upon the input signal level so that the output is at a specified Target Gain. The AGC can be configured to be either a mono or stereo input / output componen

PGA动态重构技术正适应了这种要求，用有限的资源去实现更大规模的逻辑设计，大大提高了资源利用率。但它决不仅仅是一种新型功能电路的应用，其涉及数字系统设计方法、设计思想的变革，可以使数字系统单片化的设计从追求逻辑规模转向追求逻辑的分时复用；从专用的固定功能逻辑系统转向功能可自适应进化的逻辑系统。动态重构技术是未来FPGA研究和使用方向
