The invention provides a slope control circuit. The slope control circuit includes a first diode D1, a first resistor R1 and capacitors with variable capacitance values; the first end of the first resistor R1 is used as the voltage input end of the slope control circuit; the second end of the first resistor R1 is connected to the positive electrode of the first diode D1 and the first ends of the capacitors; the second ends of the capacitors are connected to the ground; the negative electrode of the first diode D1 is the direct current power supply input end of the slope control circuit; and the positive electrode of the first diode D1 and the common ends of the first ends of the capacitors can be taken as the voltage output end of the slope control circuit. Thus, the circuit can output a linear rising voltage signal. 本申请提供了种斜率控制电路，包括：第二极管D1、第电阻R1和电容值可变的电容。其中，第电阻R1的第端作为斜率控制电路的电压输入端，第电阻R1的第二端分别与第二极管D1的正极和电容的第端相连，电容的第二端接地。第二极管D1的负极为所述斜率控制电路的直流电源输入端，第二极管D1的正极和电容的第端的公共端作为斜率控制电路的电压输出端。上述结构的电路能够输出线性上升的电压信号。
