TYPICAL APPLICATION
FET Input, Fast, High Gain Photodiode Amplier
Figure 10 shows a fast, high gain transimpedance
amplier applied to a photodiode. A JFET buffer is used
for its extremely low input bias current and high speed.
The LT1097 and 2N3904 keep the JFET biased at IDSS
for zero offset and lowest voltage noise. The JFET then
drives the LT1806, with RF closing the high speed loop
back to the JFET input and setting the transimpedance
gain. C4 helps improve the phase margin of the fast loop.
Output voltage noise density was measured as 9nV/√Hz
with RF short circuited. With RF varied from 100k to 1M,
total output noise was below 1mVRMS measured over a
10MHz bandwidth. Table 4 shows results achieved with
various values of RF and Figure 11 shows the time domain
response with RF = 499k.
