Seemingly Simple Circuits: Transresistance Amplifier, Part 2--Transimpedance Amplifier Dynamics
Dennis Feucht

In Part 1, the op-amp was approximated from a single-pole, finite gain amplifier to an infinite-gain, single-pole op-amp, and the gain of the transresistance amplifier circuit, shown repeated below, was derived. In this Part 2 we look at the consequences.

This is a throw-together project using junk box parts that can be useful whenever an interesting-looking waveform is needed for a demonstration or for the beginnings of a video test generator or curve tracer.

This article discusses how using a single synchronous buck controller can output the most common voltage rails, and accommodate a wide range of operating input voltages from 3V to 40V, and at a reasonable BOM cost.
This article explains how the latest-generation SiC FETs are ideally suited to new inverter designs with lower losses than IGBTs and proven robustness against short circuits, even at high temperatures and under repetitive stress
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
