摘要：
The CCD charge detection amplifier includes a floating diffusion charge detection node biased from a voltage reference node; a reset device coupled between the floating Diffusion charge detection node and the voltage reference node; a first source follower stage having a control node coupled to the charge detection node; and a positive feedback device coupled in series with the source follower stage and having a control node biased from the voltage reference node.
