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.
