Description

Technical field [0001] The invention is a circuit that provides voltage, especially a circuit with two -stage voltage levels. Background technique [0002] With the frequent trade exchanges between countries, a product often exports to the world for sale, but because the temperature differences in various places are quite different, the integrated circuit (IC) in the product may be affected by the temperature, and it is affected by the temperature, and it is in the temperature, and it is affected by the temperature.Some areas cannot work normally, so further adjustment of the design of the circuit needs to be adjusted.For example, in normal state, only one IC 1.9 volt of an analog voltage needs to be provided to make the IC's kick reach the ideal 0.8 volts after turning.However, if this IC is used in cold areas (such as Northern Europe), because the temperature around the surroundings is too low, the voltage of the foot after booting is only 0.35 volts, which cannot reach the id...

Problems solved by technology

[0003] Most of the circuits known to provide IC analog voltage can only provide a one-stage voltage level, such as: directly output the output voltage VOUT equal to the input voltage VIN; or Using a diode, the output voltage VOUT is equal to the input voltage VIN minus the conduction voltage of the diode

Therefore, the known circuit cannot provide the voltage of one level of IC first, and then provide the voltage of another level of IC after a period of time.
