Abstract
A method and apparatus for detecting pulse data is accomplished by a low voltage data detection circuit that includes a preamplifier circuit, an amplification stage, and a scaling circuit. The preamplifier circuit has a differential input, a predefined gain, and a maximum output limit and receives an input signal, which has a wide dynamic range. The preamplifier circuit amplifies the input signal based on the predefined gain to produce a preamplified data signal. The preamplified data signal is again amplified by the amplification stage and subsequently provided to the scaling circuit which scales the amplified data signal to a predetermined level. The resulting scaled data signal maintains the pulse width fidelity of the input data signal.
