Abstract: | This paper presents the design and comparison of two shunt feedback transimpedance amplifiers (TIAs) implemented in standard 350nm CMOS technology from Austria Microsystems. These transimpedance amplifiers are based on a folded cascode topology. The first one is a conventional folded-cascode (CFC-TIA) and the second is a modified version folded-cascod (MFC-TIA) employing a CMOS inverter at the input stage. The proposed MFC-TIA achieves a gain of 80dBΩ, 370MHz bandwidth and minimum input current noise of 1,6pA√Hz with 0.5pF total input capacitance. The achieved results show that MFC-TIAs can match the performance of CFC-TIAs with reduced implementation area, thus being a suitable solution for photo-detector array receivers. |
