The test generator includes a signal generator that generates a test pattern signal characterized by a repeating digital test pattern and an offset voltage and an input signal port adapted to receive a digital DFE output signal from the DFE, the digital DFE output signal depending on the amplification level. The test generator includes an output control port that communicates a digital command word specifying a gain to be used by the amplifier in the DFE and a threshold for determining if a signal in the DFE is a logical one or logical zero. A controller determines the amplification level by measuring a BER between the test pattern and the digital DFE output signal as a function of the threshold and the offset voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for characterizing amplifiers in decision feedback equalizers","description":"A test generator that determines an amplification level of an amplifier within a DFE and a method for determining the amplification level are disclosed.
