Abstract :
The reduction of the wavelength from 785 nm (CD) to 410 nm (Blu-ray) in optical storage systems leads to the requirement of optical receivers with high bandwidth and high sensitivity. The circuit presented achieves a bandwidth of 615 MHz with a transimpedance of 200 kΩ due to the usage of capacitive coupled distributed resistors in the feedback path.
