Abstract: A radio frequency switch generator applicable to 1.8 V and 1.2 V power supplies, which relates to the technical field of radio frequency switches. The present invention comprises a bandgap reference circuit, a linear voltage regulator circuit, a boost circuit, a ring oscillator circuit and a negative voltage circuit; wherein both the boost circuit and the ring oscillator circuit adopt an independent linear voltage stabilizing circuit as a power supply voltage source; square signals generated by the ring oscillator circuit are regarded as input signals of the boost circuit and the negative voltage circuit; and positive voltage is finally obtained after the boost circuit is subjected to double boosting twice, and negative voltage is finally obtained after the negative voltage circuit is subjected to three-level cascading.

Abstract: The present disclosure relates to an electric lift gate and a vehicle. The electric lift gate includes: two side bars opposed and spaced apart, and the two side bars being provided with a guiding groove, respectively, the guiding groove extending along a length direction of the side bar; a roller shutter assembly disposed between the two side bars, two opposite sides of the roller shutter assembly being slidably disposed in the corresponding guiding grooves, respectively; a winding assembly cooperating with the roller shutter assembly in a driving manner; and a driving assembly connected to the winding assembly, and configured to drive the winding assembly to rotate, so as to drive the roller shutter assembly to wind or unwind.
