Burst mode digital data receiver

A burst mode digital data receiver comprising

• a DC-coupled differential input amplifier circuit having a first input for receiving a burst mode digital data input signal and a second input connected to a reference voltage circuit;
• said reference voltage circuit being responsive to a detected peak amplitude of said digital data input signal and for generating a dc-voltage approximately equal to one-half of the amplitude of a received data input signal within a predetermined time of the beginning of the data input signal, and wherein
• said receiver has a first gain value during the absence of said data input signal and while the data input signal is less than its peak amplitude and has a second gain value approximately equal to twice the first gain value for a predetermined time after the peak amplitude of the data input signal is reached.

A digital data receiver comprising

• a DC-coupled differential amplifier circuit having a first input for receiving a digital data input signal, a second input connected to a voltage reference circuit, and a data output;
• and
• said voltage reference circuit being connected in a feedback loop between said data output and said second input for detecting a peak amplitude of said digital data input signal and generating a feedback signal to said amplifier circuit, resulting in said receiver having a first gain value during the absence of said data input signal and while the data input signal is less than its peak amplitude and having a second gain value approximately equal to two times the first gain value for a predetermined time after the peak amplitude of the data input signal is reached.
