Design of CMOS Differential Transimpedance Amplifier
Elektronika ir Elektrotechnika, 2015 This paper explores the design of a differential transimpedance amplifier (TIA) integrated circuit for use in optical time domain reflectometer (OTDR) optical receivers (OR). All dependences between primary TIA design variables including OTDR laser pulse width, OR bandwidth, and TIA feedback resistance, are defined.

Broad-Band Design Techniques for Transimpedance Amplifiers [PDF]
IEEE Transactions on Circuits and Systems I: Regular Papers, 2007 In this paper, a novel bandwidth enhancement technique based on the combination of capacitive degeneration, broad-band matching network, and the regulated cascode (RGC) input stage is proposed and analyzed, which turns the transimpedance amplifier (TIA) design into a fifth-order low-pass filter with Butterworth response.

Pre-current amplifier based transimpedance amplifier for biosensors
International Journal of Reconfigurable and Embedded Systems (IJRES), 2022 In this paper, we present current amplifier based transimpedance amplifier (TIA) for biosensor applications. Proposed design has low-noise, high Transimpedance gain that can be used for low current measurement applications. The current amplifier based TIA is implemented in order to resolve the fabrication issues related to high value feedback resistor.

Constant-bandwidth adaptive transimpedance amplifier
Electronics Letters, 2007 A new CMOS transimpedance amplifier (TIA) with variable gain for optical fibre communication receivers is presented. The proposed configuration is realised in a low-cost digital 0.35 µm CMOS process fed from a single 1.8 V voltage supply. A 56–68 dBΩ transimpedance gain variation range is attained with 1 GHz bandwidth.
