Ultra‐low‐noise large‐bandwidth transimpedance amplifier
International Journal of Circuit Theory and Applications, 2014SummaryEquivalent input current noise and bandwidth are the most relevant parameters qualifying a low‐noise transimpedance amplifier. In the conventional topology consisting of an operational amplifier in a shunt‐shunt configuration, the equivalent input noise decreases as the feedback resistor (RF), which also sets the gain, increases.

Design of linear transimpedance amplifiers
ASICON 2001. 2001 4th International Conference on ASIC Proceedings (Cat. No.01TH8549), 2002Current-to-voltage converters are important building blocks in analog-mixed signal processing circuits. In this paper, two very simple circuits of transimpedance amplifier used to realize a linear current-to-voltage conversion are presented. The circuits operation is not based on any charge accumulation process and the implementation of the circuits ...

A CMOS transimpedance amplifier for optical wireless communications
2013 International Symposium on Intelligent Signal Processing and Communication Systems, 2013A low-cost transimpedance amplifier (TIA) suitable for optical wireless communications is presented. The shunt-feedback TIA is designed using a feedforward current amplifier (CA). The bandwidth of the CA-TIA exhibits low sensitivity to the TIA gain. The optical receiver front-end is validated by both simulation and measurement.

A low noise transimpedance amplifier for optical receiver
Review of Scientific Instruments, 2021In this paper, a regulated cascode (RGC) structure and a shunt-feedback transimpedance amplifier are cascaded. By analyzing the average input-referred noise current, this paper used the method of adjusting the metal–oxide–semiconductor size and increasing the transimpedance gain to optimize the circuit noise characteristics without introducing ...

Gigahertz low noise CMOS transimpedance amplifier
Proceedings of 1997 IEEE International Symposium on Circuits and Systems. Circuits and Systems in the Information Age ISCAS '97, 2002A new class of low noise CMOS common gate transimpedance amplifier is described. What is novel about the design is the total isolation of the photodiode capacitance from determining the -3 dB bandwidth. HSPICE simulations of this amplifier were conducted using the Tritech 0.6 /spl mu/m CMOS process.
