Abstract
A pixel sensor cell including a column circuit, a design structure for fabricating the pixel sensor cell including the column circuit and a method for operating the pixel sensor cell including the column circuit are predicated upon the measurement of multiple reference data point and signal data point pairs from a floating diffusion at a variable capacitance. The variable capacitance is provided by excluding or including a transfer gate transistor capacitance in addition to a floating diffusion capacitance. Such a variable capacitance provides variable dynamic ranges for the pixel sensor cell including the column circuit.
