摘要：
In this paper we report on the design and test of a 14-channel VLSI chip to perform the current to frequency conversion for parallel plate strip ionization chambers. The chambers measure the intensity and the geometrical characteristics of a therapeutical beam. (C) 1998 Elsevier Science B.V. All rights reserved.
