Abstract
PURPOSE: To avoid the influence of power ripple, by inserting a series circuit consisting of a capacitor and a resistor between a power supply input terminal and an inverting input terminal.
CONSTITUTION: A series circuit 10 consisting of a capacitor 9 and a resistor 8 for DC cut-off introduces only ripple components from a power supply input terminal 6 to an inverting input terminal 3. As the capacitor 9, a sufficiently larger capacitance not affecting the ripple voltage for the voltage division with resistors 2 and 8 is used. When a value of the resistor 8 is set so that a value of K/G.VR (where; G is the amplification factor of an amplifier) is applied to a termial 3, an output of KVR due to the ripple voltage mixed in an amplifying circuit 4 and an output as -KVR due to the ripple voltage at the terminal 3 can be cancelled with each other.
