First Claim
1. A receiver for translating an input signal to a conditioned analog signal for digital processing, the receiver comprising:
- a first amplifier receiving the input signal as two differential input signals and modifying the two differential input signals for providing a difference between the two differential input signals as a first signal;
a clock source for providing a clock signal;
a second amplifier receiving the clock signal from the clock source and the first signal from the first amplifier and holding information in the first signal in response to a timing of the clock signal and providing the conditioned analog signal with information from the first signal.

Abstract
A receiver includes an interface for translating an optical signal into two differential electrical signals for a first amplifier. The first amplifier modifies the two differential electrical signals to produce a first signal that is the amplitude of difference between the two differential electrical signals, which contains the information from the optical signal. A variable gain track and hold amplifier (VGTHA) receives the first signal and a clock signal and provides a conditioned analog signal for digital processing. A clock source provides the clock signal, which is aligned with the peak amplitude of the first signal.
