Abstract
A signal level monitoring circuit for outputting either voltage or current corresponding to an input signal level, includes a variable gain unit for obtaining a predetermined output level without being dependent on a gain, when the input signal level is a predetermined reference input level; and an offset adding unit for outputting a predetermined reference output level by adding an offset level to the output level of the variable gain means, when the input signal level is the predetermined reference input level. According to the present invention, it is possible to adjust precisely and surely the gain and the offset voltage based on simple adjusting steps in a short time and only once.
