Abstract
Methods and apparatuses using four-way-shared readout circuits to increase pixel fill factor. Embodiments consolidate circuits from several pixels, reducing the number of components in each pixel and this increasing the fill factor of each pixel. Additionally, embodiments use “straight gate” transfer gates to increase the readout speed and symmetry of the smaller pixels.
