Photo-receiver arrangement

Abstract

A photo-receiver arrangement includes a photo-sensor that captures light being incident thereon within a predetermined range of light intensity values. The photo-sensor also converts the captured incident light into a first electrical signal. A pre-scaler is connected to an output of the photo-sensor for producing a second scaled electrical signal based on and corresponding to said first electrical signal input into the pre-scaler; and a preamplifier is connected to an output of the pre-scaler for amplifying said second scaled electrical signal input into the preamplifier. The preamplifier has a dynamic range of at least substantially linear gain. The pre-scaler and the preamplifier are designed in a mutually matching configuration such that the second scaled electrical signal falls within the said dynamic range of the preamplifier for any light intensity value falling into said predetermined range of light intensity values.
