发明名称 LOW DROP-OUT REGULATOR WITH DISTRIBUTED OUTPUT NETWORK
摘要 Disclosed is a low drop-out voltage regulator circuit with a distributed output network coupled to a pixel array for use in image sensor circuitry. The regulator circuit comprises voltage regulating circuitry and a distributed output network, wherein the distributed output network comprises drive transistors disposed along and connected between a supply track and an output track. The spatial distribution of the drive transistors improves heat dissipation within the regulator circuit, and a combination of low current flow and regulated output voltage reduces IR drop across the output track. The improved heat dissipation increases device lifespan and performance, whereas the reduction in IR drop across the output track provides better pixel response, readout uniformity, and image quality.
