Abstract: A readout system for X-ray CCDs based on an improved architecture is presented; by optimizing several critical circuit blocks along the analog signal chain, the conflict between the readout speed and readout noise is greatly alleviated. Using CCD47-10 as its target CCD, the readout system has achieved 8.6e- readout noise and 142 eV FWHM at 5.9 keV Mn m Kα under a pixel rate of 80 kHz. Also its performance of imaging has been investigated.
