8.2.2.1 Design Requirements
The objective of this design is to achieve:
- Smallest solution size
- Transimpedance output of 0.1 V to 4 V for a 0-µA to 90-µA input with a bandwidth of 1 MHz
- The voltage divider is designed to provide a minimum amplifier output of 0.1 V when the photodiode current is zero (dark current) to prevent the amplifier from saturating to the negative rail
