| Abstract: | Design of scanning signal generator circuit for transistor characteristic exhibit instrument base on 555 timer was introduced in this paper. Synchronous sawtooth wave and ladder wave trigger were generated by using 555 timer. Then the scanning signal with well linearity could be obtained. The experiment results demonstrate that the circuit is simple and useful, and the wave display is better than the one of general transistor characteristic exhibit instruments. |
