Title:
NOISE RESISTANCE IMPROVING CIRCUIT FOR AMPLIFIER
Document Type and Number:
Japanese Patent JPH088657
Kind Code:
A
Abstract:
PURPOSE: To improve the noise resistance of an amplifier.
CONSTITUTION: This circuit has transmission lines 9 and 11 connected to input terminals 3 and 5 of a differential amplifier 1 and a capacitor 13 connected between transmission lines 9 and 11, and the lengthes of transmission lines 9 and 11 from terminals 13a and 13b of the capacitor 13 to input terminals 3 and 5 of the differential amplifier 1 are made equal to each other. Since the high frequency noise penetrating one transmission line passes through the capacitor 13 and is equally superposed on both of transmission lines 9 and 11, the influence of the noise upon the differential amplifier 1 is cancelled.
