【文章內(nèi)容簡介】 circuit to generate sine vibration, to obtain the necessary frequency. But can also Synthesis technology to obtain the necessary 9 rate. Frequency of use of technology into the signal generator, often referred to as synthetic signal generator. 3 The implementation methods of signal generator The realization of the function signal generator method usually have the following kinds: (1) the ponents with division: it is usually function generator single function generator and frequency is not high, its work is not very stable, not easy debugging. (2) can be made by the transistor, the opamp IC etc, more universal device is made with special function signal generator IC produce. Early function signal generator IC, such as L8038, BA205, XR2207/2209 etc, the functions of them less, precision, frequency cap 300kHz, unable to produce only higher frequency of signal, adjust the way also not enough flexibility, frequency and occupies emptiespared to cannot independent regulation, both affecting each other. (3) use monolithic integrated chip function generator: can produce various waveform, achieve the high frequency, and easy to debug. In view of this, the American beauty developed a new generation letter ICMAX038 function signal generator, it overes the (2) chip shortings, can achieve higher technical index, is the chip deficits. MAX038 frequency and high accuracy, good, therefore it is called a highfrequency precision function signal generator IC. In PLL, vco, frequency synthesizer, pulse width omdulatros etc circuit design, selection of devices are MAX038.
