Abstract: PROBLEM TO BE SOLVED: To provide an amplifier circuit capable of performing stable negative feedback while obtaining a high open loop gain, and which has a wide frequency band of the gain. SOLUTION: A MOS transistor M11 constitutes a current buffer whose gate is grounded, and input currents ia are outputted to the drain.

The terminal A and the terminal V whose phases are the same are connected in crossing by using two amplifying parts in a figure 2 so that a differential amplifier circuit which outputs a differential voltage corresponding to input differential currents can be constituted. Also, the co-phase voltage being the output is fed back to a terminal CM, and the positive feedback of the co-phase voltage is offset.  Thus, the high range polar frequencies of a capacitor CL and a capacitor C11 are made fixed regardless of the gains so that stable feedback can be realized with a high open loop gain.
