锁定放大是微弱信号检测的重要手段。基于相关检测理论,利用开关电容的开关实现锁定放大器中乘法器的功能,提出开关电容和积分器相结合以实现相关检测的方法,并设计出一种锁定放大器。该锁定放大器将微弱信号转化为与之相关的方波,通过后续电路得到正比于被测信号的直流电平,为后续采集处理提供方便。测量数据表明锁定放大器前级可将10-6 A的电流转换为10-1 V的电压,后级通过带通滤波器级联可将信号放大1×105倍。该方法在降低噪声的同时,可对微弱信号进行放大,线性度较高、稳定性较好。 Abstract: Lock-in Amplifying(LIA)is one of important means for weak signal detection. Based on cross-correlation detection theory, switch in the swithched capacitor was used as multiplier of LIA, and a new method of correlation detection was proposed combining swithched capacitor with integrator. A kind of LIA was designed which can convert the weak signal to square-wave, then DC proportional to measured signal was obtained through follow-up conditioning circuit, providing convenience for signal acquisition and processing. The measured data shows that the electric current(10-6 A) can be changed into voltage(10-1 V) by LIA, and the signal is magnified 1×105 times by cascade band-pass filter. The noise is suppressed and the weak signal is amplified. It has the advantages of good linearity and stability.

1. Download the version you want: * Version 1.3.4 (30 Aug 2007) -- this is the latest version for UNIX/Linux and Windows * Previous versions 2. Unzip the file, which will create a directory called klt and place all the files there 3. Compile and run the code * On UNIX / Linux, move to the klt directory, type make. Now try some examples, by typing example1, etc. * For Microsoft Visual C++ 6.0, open the klt.dsw file, compile, and run. Change the constant in main.cpp to run the different examples. * For Microsoft Visual Studio .Net/7/8, open the klt.sln file, compile, and run. Change the constant in main.cpp to run the different examples. 4. Notice that, for your convenience, unofficial copies of the User and Reference Manuals can be found in the doc directory.

GNU_Radio GNU radio is a free/open-source software toolkit for and the content is controlled by a handful of organizations. Cell building software radios, in which software defines the phones are a great convenience, but the features your phone transmitted waveforms and demodulates the received supports are determined by the operator s interests, not yours. waveforms. Software radio is the technique of getting code A centralized system limits the rate of innovation. Instead of as close to the antenna as possible. It turns radio hardware cell phones being second-class citizens, usable only if problems into software problems.

A major societal challenge for the decades to come will be the delivery of effective medical services while at the same time curbing the growing cost of healthcare. It is expected that new concepts-particularly electronically assisted healthcare will provide an answer. This will include new devices, new medical services as well as networking. On the device side, impressive innovation has been made possible by micro- and nanoelectronics or CMOS Integrated Circuits. Even higher accuracy and smaller form factor combined with reduced cost and increased convenience of use are enabled by incorporation of CMOS IC design in the realization of biomedical systems. The compact hearing aid devices and current pacemakers are good examples of how CMOS ICs bring about these new functionalities and services in the medical field. Apart from these existing applications, many researchers are trying to develop new bio-medical solutions such as Artificial Retina, Deep Brain Stimulation, and Wearable Healthcare Systems. These are possible by combining the recent advances of bio-medical technology with low power CMOS IC technology.
