Usually the plus of the voltage-preamplifier we used is changeless or 2-modes (×1 or ×10), and the value is low (×10). But in the practical application, the energy of the particles detected are complicated. Especially, when the particles which are detected are unknown, it will be advantageous to the result to select a proper plus. So it will be great beneficial for the practical application to design a bran-new voltage-preamplifier which has bigger plus comparing to the amplifier we used now and could select a proper plus for the experiment automatically. This article introduces a design of a kind of new voltage-preamplifier with a bigger plus (×20) than traditional voltage-preamplifiers and whose plus can be controlled continuously. The most important of all is that this voltage-preamplifier can select a appropriate plus for the experiment automatically by the order of the handlers. It adjusts the plus by the information from the sensor to the order. In this design we control the output-signal from 100∼200 mV. And then, this paper introduces the simulation of the amplifier’s working process by Multisim10.0 and Multisim10.0 Proteus ISIS.
