Abstract:
An understanding of the noise is required for a receiver’s
performance to be precisely characterized. The amount of noise present in a
receiver will be the primary factor that determines the receiver’s sensitivity.
In this study, the definition of noise in infrared communication is discussed
to demonstrate the effects of receiver noise on performance for adjustable bootstrap
transimpedance and voltage feedback receiver amplifier. The noise sources that
are commonly found in an optical wireless receiver are then discussed, including
noises that are of optical as well as of electrical origin. The equivalent circuit
model that will describe the noise performance of the bootstrap transimpedance
and voltage feedback amplifier circuit shows, that the input noise current density
is flat 380 pV/
