Abstract：
To meet the physics requirement, the time resolution of TOF (Time-of-flight) detector of the BESⅢ (Beijing Spectrometer Ⅲ) is required to be less than 90ps (rms), and the FEE (front end electronic) must contribute less than 25ps. This paper describes the prototype design of BESⅢ's TOF readout system (including time and amplitude measurement circuits).Preliminary results for prototypes of TOF front end electronics are given.
