Description

technical field [0001] The invention relates to electronic circuit technology, in particular to a ladder wave generating circuit. Background technique [0002] At present, in the field of electronic circuit design, the staircase wave is a commonly used analog signal. The traditional ladder wave generator generally has the following two schemes: the first scheme is as follows figure 1 As shown, it consists of a square wave generator, a differential circuit, a limiting circuit, an integral accumulation circuit, an electronic switch circuit, a comparator and an oscillation circuit. Both have sharp pulse waveforms. At this time, to only take the sharp pulse above, it is necessary to filter out the lower half of the waveform through the limiter circuit. When these pulses pass through the integration and accumulation circuit, a sharp pulse is accumulated to a fixed value, and the same value will be increased when the next pulse arrives, so the output forms a staircase waveform....

AI Technical Summary

Problems solved by technology

It can be seen that this solution is realized by integrated operational amplifiers or transistors. Although it is simple, it has obvious disadvantages: it is very difficult to generate a ladder wave whose level can be adjusted at will, and all circuits such as square wave generators and comparators need to be rebuilt Setting and adjustment will cause the circuit structure to become complicated

The second option is as Figure II As shown, including clock signal generator, counter, CPU and digital-to-analog converter, it is mainly realized by programmable devices to control the generation of ladder waves. Compared with the first scheme, this scheme can obtain flexible and changeable waveforms, but This solution requires programming, which limits its application occasions. On the other hand, the high-speed processor costs more, which further limits its application.
