Bandwidth enhancement for transimpedance amplifiers [PDF]
IEEE Journal of Solid-State Circuits, 2004 A technique for bandwidth enhancement of a given amplifier is presented. Adding several interstage passive matching networks enables the control of transfer function and frequency response behavior. Parasitic capacitances of cascaded gain stages are isolated from each other and absorbed into passive networks.

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.

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.

A CMOS Tunable Transimpedance Amplifier [PDF]
IEEE Microwave and Wireless Components Letters, 2006 A tunable transimpedance amplifier (TIA) is presented in this letter. By incorporating a mechanism for gain and bandwidth tuning, the TIA can be adjusted to achieve optimum circuit performance with a lowest bit-error-rate (BER) for high-speed applications. The proposed circuit is implemented in a 0.18-mum CMOS process. Consuming a dc power of 34mW from

Transimpedance instrumentation amplifier based on current inversion [PDF]
2017 15th IEEE International New Circuits and Systems Conference (NEWCAS), 2017 this paper presents a novel instrumentation amplifier operating a differential current measurement from a resistive bridge. The proposed transimpedance instrumentation amplifier is constructed with two voltage opamps. One opamp is used to realize the current inversion and the second as a single input transimpedance amplifier.

Effect of the Transimpedance Amplifier Topology on the Photoplethysmography Signal
IECON 2022 – 48th Annual Conference of the IEEE Industrial Electronics Society, 2022 Photoplethysmography (PPG) is a widely used technique to extract physiological information non-invasively. Besides other factors, the transimpedance amplifier (TIA) topology choice has an impact on the PPG signal. This study presents a novel quantitative evaluation of seven different resistive TIA topologies in terms of four different Signal Quality ...

CMOS transimpedance amplifier for biosensor signal acquisition [PDF]
2014 IEEE International Symposium on Circuits and Systems (ISCAS), 2014 We present a 1-GΩ CMOS transimpedance amplifier (TIA) suitable for processing sub-nA-level currents in electrochemical biosensor signal-acquisition circuits. Use of a two-stage active transconductor provides resistive feedback in place of a single large-area linear resistor. We engineer the TIA feedback loop to suppress output offset caused by dc input

Transimpedance Amplifier [Circuit Intuitions] [PDF]
IEEE Solid-State Circuits Magazine, 2020 Discusses the technology of a transimpedance amplifier (TIA). A TIA is a two-port device that converts an input current in one port to an output voltage in another port. A TIA is expected to have a low input impedance, so as to absorb all the current produced by the PD, and a high output impedance, so as to have a high gain. We reviewed two TIA designs
