The Transimpedance Amplifier [A Circuit for All Seasons]
Many of today''s communication sys-tems incorporate a transimpedance amplifier (TIA). Although the TIA concept is as old as feedback ampli-fiers , it was in the late 1960s and early 1970s that TIAs
Transimpedance amplifier
In electronics, a transimpedance amplifier (TIA) is a current to voltage converter, almost exclusively implemented with one or more operational amplifiers (opamps).

The transimpedance in a CFA serves the same function as gain in a VFA; it is the parameter that makes the perfor-mance of the op amp dependent only on the passive parameter values.

Current Feedback Amplifier
The current feedback architecture has very high slew rate and the small-signal bandwidth is fairly constant for all gains. Current feedback amplifiers are used in broadcast video systems, radar
Very-low frequency capacitively coupled AC amplifier with a current
In this paper, we propose the idea of using transimpedance amplifiers, in lieu of operational amplifiers (OAs) or transconductance amplifiers (OTAs) to design capacitively coupled AC amplifiers.
The_Current-Feedback_Op_Amp:_A_High-Speed_Building_Block
It is now obvious why the amplifier is known as “current-feedback.” The output voltage is responsive to a current at the low impedance inverting input node (the emitter of Q 1) that interacts with the open

MT-034: Current Feedback Op Amps
In this tutorial the two basic op amp topologies—voltage feedback (VFB) and current feedback (CFB)—are discussed in more detail, and the differences are pointed out.

Figure 6 9 1: Current feedback amplifier equivalent. An equivalent model of a noninverting current feedback amplifier is shown in Figure 6 9 1. This device uses a transimpedance
What you need to know about transimpedance amplifiers part 1
TIAs are conceptually simple: a feedback resistor (RF) across an operational amplifier (op amp) converts the current (I) to a voltage (VOUT) using Ohm''s law, VOUT = I × RF. In this series of blog posts, I will
