OPTICAL DETECTOR AMPLIFIER
Figure 4-13
shows the MCP6021 op amp used as a
transimpedance amplifier in a photo detector circuit.
The photo detector looks like a capacitive current
source, so the 100 kΩ resistor gains the input signal to
a reasonable level. The 5.6 pF capacitor stabilizes this
circuit and produces a flat frequency response with a
bandwidth of 370 kHz.
