The LT6233 is applied as a transimpedance amplifier with
an I-to-V conversion gain of 10kΩ set by R1. The LT6233
is ideally suited to this application because of its low in-
put offset voltage and current, and its low noise. This is
because the 10k resistor has an inherent thermal noise of
13nV/√Hz or 1.3pA/√Hz at room temperature, while the
LT6233 contributes only 2nV and 0.8pA/√Hz. So, with
respect to both voltage and current noises, the LT6233 is
actually quieter than the gain resistor.
The circuit uses an avalanche photodiode with the cathode
biased to approximately 200V. When light is incident on
the photodiode, it induces a current IPD which flows into
the amplifier circuit. The amplifier output falls negative
to maintain balance at its inputs. The transfer function
is therefore VOUT = –IPD 10k. C1 ensures stability and
good settling characteristics. Output offset was measured
at better than 500V, so low in part because R2 serves to
cancel the DC effects of bias current. Output noise was
measured at below 1mVP-P on a 20MHz measurement
bandwidth,withC2shuntingR2’sthermalnoise. Asshown
in the scope photo, the rise time is 45ns, indicating a signal
bandwidth of 7.8MHz.
