I often need a simple function generator. Just to generate a certain frequency. After all the years I ve worked with electronics, I still haven t got me one. Even though I need it now and then, I just couldn t seem to justify the cost of one. So, standard solution - build one yourself. I designed a simple sinewave generator based on a analog Devices AD9832 chip. It will generate a sinewave from 0.005 to 12 MHz in 0.005 Hz steps. That s pretty good, and definitely good enough for me ! But while waiting for the AD9832 chip to arrive, I came up with a very simple version of the DDS synth, using just the 2313 and a resistor network.

Design of Integrated Circuits for Optical Communications deals with the design of high-speed integrated circuits for optical communication systems. Written for both students and practicing engineers, the book systematically takes the reader from basic concepts to advanced topics, establishing both rigor and intuition. The text emphasizes analysis and design in modern VLSI technologies, particularly CMOS, and presents numerous broadband circuit techniques. Leading researcher Behzad Razavi is also the author of Design of analog CMOS Integrated Circuits.

这是I2c网关Id独立烧写程序， 烧写的ID必须要求是：“0~9”、“a~z”、“A~Z”的16为字符才能烧写成功。 其中当是输入的小写字母时，自动转换为大些烧入。 如： 1） # ./burnID 0123456789abcdef 烧入的是：0123456789ABCDEF 2] # ./burnID 0123456789@ cdef 烧入不成功，因为有其他字符 3） # ./burnID 0123456789abcdefDfs 烧入也不成，因为超过16个字符 built-in analog anti-aliasing filters, four 10bit analog-to-Digital converters, and proprietary digital gain/clamp controller, high quality Y/C separator to reduce cross-noise and high performance free scaler.

The LM35 of National Semiconductors that is used in this project is a precision centigrade temperature sensor, which has an analog output voltage. It has a range of -55潞C to +150潞C and a accuracy of 卤0.5潞C . The output voltage is 10mV/潞C . The output voltage is converted by the AD convertor of the AT Mega8. The temperature is displayed on an LCD module. In this example the thermometer has a range of 0潞C to 40潞C and a resolution of 0.5潞C. If you want to have a readout in Fahrenheit you can use the LM34.
