description The invention provides an implementation method of a super pixel circuit with an embedded low dropout regulator, which is realized by integrating an LDO (Low Dropout Regulator) into a 2 * 2 pixel array, and embedding the LDO into the middle position of a 2 * 2 pixel array layout to form a digital sea and simulation island layout, realize digital and simulation power supply isolation and remarkably reduce equivalent noise charges of the circuit. The reference voltage of the LDO is realized by adopting an off-chip reference voltage chip, so that the consistency of the reference voltage of the LDO in the pixel array can be ensured. Compared with the traditional global power supply and full-column power supply mode, the implementation method of the integrated LDO super pixel circuit provided by the invention has the advantages that the power supply voltage drop on the pixel unit is obviously reduced, so that the power supply consistency of a pixel array chip is improved. 本发明提出了一种内嵌低压差线性稳压器的超级像素电路实现方法，通过将LDO集成到2×2
