Problems solved by technology

[0006] The pulse generation circuit in the prior art is based on the traditional inverter gate method to generate delay. Due to the influence of its technology and the use of ambient temperature, the delay error range of the delay circuit is -80% to +120%. That is, the delay error range is large, and the generated pulse width signal is inaccurate
