Abstract:This paper presents a new wideband high gain CMOS transimpedance amplifier without using any inductor. In the proposed TIA, gain enhancing path is introduced in the active voltage-current feedback TIA topology to increase both the gain and bandwidth. This path increases the transconductance of the proposed TIA which reduces the input resistance and leads to bandwidth extension. Additionally, for utilizing the benefit of this topology, cascading of common source stage is also done to increase the gain further w… Show more
