| description | The invention discloses an energy collection low-voltage cold start circuit suitable for indoor sunlight, and relates to the field of solar energy collection. The circuit comprises a ring oscillationcircuit, a two-phase clock drive circuit, a linear charge pump, an off-chip filter capacitor, an off-chip energy storage capacitor, an enable tube first PMOS tube, an enable tube second PMOS tube, a third PMOS transistor, fourth PMOS transistor, fifth PMOS transistor and sixth PMOS transistor for outputting branch voltages to the linear charge pump, a voltage reference, a current reference, a hysteresis comparator, a first inverter and a second inverter. According to the invention, starting can be carried out under ultra-low voltage; wide-range voltage input can be satisfied; after cold startand work start, the output of the internal linear charge pump directly charges the off-chip energy storage capacitor; when the off-chip energy storage capacitor stores enough energy, a relatively highvoltage value is output to |
