Claim 16:
17. A signal quantizing method, applicable to the readout circuit of claim 16, comprising:
the signal sampler collecting an analog signal from each of the plurality of channels;
the plurality of integrators converting the analog signal collected from each of the plurality of channels into an electric charge signal, respectively;
the signal processor receiving the electric charge signals output by the plurality of integrators in sequence;
the signal processor sampling and holding each of the electric charge signals; and
the analog-digital converter performing an analog-digital conversion on sampled and held electric charge signal to obtain a quantized result of the electric charge signal;
wherein the signal processor sampling and holding each of the electric charge signals comprises:
the randomizing circuit randomizing an order in which the electric charge signals are held, and
the signal processor holding the electric charge signals in sequence based on a randomized order.
