Problems solved by technology

If the voltage difference between the first input signal IN and the second input signal INB is too small, the differential amplifier may not be able to fully amplify the voltage difference between the first input signal IN and the second input signal INB, and therefore, the first and the second output signals OUT and OUTB cannot be correctly identified

Embodiment Construction

[0021] Hereinafter, a differential amplifier according to the present invention will be described in detail with reference to the accompanying drawings.

[0022] Figure 4 is a block diagram showing a differential amplifier according to an embodiment of the present invention.

[0023] Such as Figure 4 As shown, the differential amplifier amplifies the voltage difference between the first input IN and the second input INB and outputs the first output OUT and the second output OUTB. In addition, the differential amplifier receives the first and second outputs OUT and OUTB as first and second feedback signals OUT_FD and OUTB_FD to re-amplify the voltage difference between the first output OUT and the second output OUTB.

[0024] Figure 5 to depict Figure 4 A schematic diagram of the difference amplifier is shown.

[0025] Such as Figure 5 As shown, the differential amplifier includes a first amplification unit 100 , a second amplification unit 200 and an initialization ...

Abstract

A differential amplifier includes an amplification unit and a feedback unit. The amplification unit amplifies a voltage difference between a first input signal and a second input signal and outputs afirst output signal and a second output signal. The feedback unit amplifies a voltage difference between a first feedback signal based on the first output signal and a second feedback signal based onthe second output signal.

Description

technical field [0001] The present invention relates to differential amplifiers; and more particularly, the present invention relates to differential amplifiers for reliably performing amplification operations. Background technique [0002] A difference amplifier multiplies the voltage difference between two inputs by a constant factor to obtain a differential gain. Many integrated circuits, including dynamic random access memory (DRAM), use differential amplifiers for signal amplification. [0003] figure 1 A typical block diagram of a difference amplifier. [0004] Such as figure 1 As shown, the differential amplifier 1 amplifies the voltage difference between the first input IN and the second input INB and outputs a first output OUT and a second output OUTB. [0005] figure 2 for figure 1 The schematic circuit diagram of the difference amplifier shown in . [0006] as in figure 2 As shown in , the differential amplifier 1 includes a first amplifying unit 10 , a ...
