Abstract
That a PMOSFET is used to substitute the NMOSFET in APS as reset transistor is presented.By optimizing and simulating based on the 0.25μm CMOS technology
the results show that the new structure has higher signal-to-noise ratio
wider output swing
wider dynamic range and faster readout speed under the same condition.
