Abstract:
1. A CMOS image sensor pixel array, wherein each pixel of the array includes at least one pixel circuit, comprising: at least two Bulk Charge Modulated Device (BCMD) transistors coupled to a single photodiode, wherein said BCMD transistors have the capability of storing charge transferred from the photodiode for all the pixels of the array simultaneously, thereby performing the global shuttering function; said stored charge being accumulated in said photodiodes during at least two different integration times; peripheral circuitry; and first and second transfer gates, wherein the first transfer gate is electrically connected between the photodiode and a first one of the BCMD transistors, wherein the second transfer gate is electrically connected between the photodiode and a second one of the BCMD transistors, and wherein each of the BCMD transistors has a gate electrically connected to a row address line.
