New Sample of Transimpedance Amplifier
ABSTRACT This paper presents a dual feedback transimpedance amplifier (TIA) with a modified regulated-cascode (RGC) topology that employs a negative resistance-capacitance (NRC) network to enhance both bandwidth and noise performance. TIAs are conceptually simple: a feedback resistor (RF) across an operational amplifier (op amp) converts the current (I) to a voltage (VOUT). Designed for next-generation 400G and 800G optical transceivers, this new CHR1065 product family combines outstanding performance with practical. These applications place great emphasis on the multifunctionality and scalability.
