【 摘 要 】

The development of an analog read-out channel for time projection chambers (TPC) is presented both in schematic and layout. Structure of the channel consists of a preamplifier, fourth order shaper and differential buffer. The channel operates with positive and negative polarities of input charge. The prototype has the following features: dynamic range of 100 fC for both polarities, 20 mv/fC of sensitivity for differential output, peaking time - 160 ns, ENC -
