Abstract :
A BiCMOS optoelectronic integrated circuit (OEIC) for optical storage systems containing photodiodes and transimpedance amplifiers with a reduced offset voltage is presented. A reference transimpedance amplifier and a low-offset operational amplifier are implemented for offset reduction. A -3 dB frequency of 58 MHz and a sensitivity of 25 mV/μW at 638 nm have been measured
