Embodiment Construction
[0025] Embodiments of the present invention will be described below based on the drawings.
[0026] figure 1 It is a diagram showing a configuration example of an amplifier circuit in one embodiment of the present invention. The amplifier circuit in this embodiment includes an amplifier unit 10 , a correction circuit unit 30 , and a control unit 50 . The amplifying unit 10 has an input circuit unit that receives an input signal, and a load circuit unit that is used as a load and is composed of a variable resistance circuit controlled to a desired resistance value, and amplifies a differential input with a specific gain (magnification). signal and output.
[0027] In the amplifier unit 10 , the NMOS transistors 11A and 11B included in the input circuit unit form drive elements in the differential amplifier unit. The gate of NMOS transistor 11A is connected to input terminal IN to which one signal of a differential input signal is input, and the source is connected to curren...
