Low Noise Amplifiers for Small and Large Area Photodiodes
Design Note 399
Glen Brisebois Introduction
Photodiodes can be broken into two categories: large
area photodiodes with their attendant high capacitance
(30pF to 3000pF) and smaller area photodiodes with
relatively low capacitance (10pF or less). For optimal
signal-to-noise performance, a transimpedance amplifier consisting of an inverting op amp and a feedback
resistor is most commonly used to convert the photodiode current into voltage. In low noise amplifier design,
large area photodiode amplifiers require more attention
to reducing op amp input voltage noise, while small area
photodiode amplifiers require more attention to reducing
op amp input current noise and parasitic capacitances. Small Area Photodiode Amplifiers
Small area photodiodes have very low capacitance,
typically under 10pF and some even below 1pF. Their
low capacitance makes them more approximate current
sources to higher frequencies than large area photodiodes. One of the challenges of small area photodiode
amplifier design is to maintain low input capacitance
so that voltage noise does not become an issue and
current noise dominates.
Figure 1 shows a simple small area photodiode amplifier using the LTC В®6244. The input capacitance of
