查询词典 preamplifier

Next, the following points are emphasized:(1) The design of photoelectric conversion preamplifier circuit. In order to improve the measurement accuracy of luminometer and ensure linear relationship of the photoelectric, operational amplifiers is designed as current-voltage converter form, on the one hand, it is available to zero-load effect; on the other hand, short-circuit current can be transformed into a voltage volume through the feedback resistor, it is equivalent to voltage drop flowed through a load resistor on the actual effect.

其次，本文重点做了以下工作：(1)光电转换前置放大电路的设计：为了提高照度计的测量准确度，确保光电间的线性关系，本设计把运算放大器接成电流电压变换器的形式，一方面可得到零负载效应；另一方面，短路电流通过反馈电阻变成电压量，实际效果相当于流过一个负载电阻形成的压降。
