Re: Well derived analysis but needs Part 3

Thanks  for your comments and suggestion. There actually is a Part 3, of sorts: a previous article titled "Case Study: Medical Laser System; Part 2: Photodiode Amplifier" along with Parts 3 and 4 that cover the dynamics.

Well derived analysis but needs Part 3

Your two-part Transimpedance Amplifier Dynamics article is written clearly with the goal of the readers being able to use your final derivations.  It's been a number of years since I was paid to implement a Transimpedance Amp circuit (which worked very well though not as fully analyzed as you have done here.  To not scare away new mixed-signal engineers, I would propose a Part 3 to demonstrate a real world usage of these equations.  It doesn't have to be complicated. There are only a handful of parts involved.  I wouldn't include complications introduced by various op-amps.  Thanks  again for a stimulating analog article,

Previously we looked at the electronics and sensors involved in data acquisition systems (DASs). Now we look at what to do with the raw ADC data once it is acquired.
This is a tutorial presentation of principles of instrumentation that is typically multi-channel, medium to high resolution (12 to 20 bits) and relatively slow - slower than oscilloscopes in sample rate
Continuing the chat from last time, we turn now to a circuit-related topic, that of current waveforms. The typical converter input waveform is shown with a static (dc) component and a ripple (ac) component
Semiconductor companies have now had fully-differential amplifiers in their product lines for a few years, though these amplifiers have been in leading-edge electronics for decades. These diff-amps are differential not only at their input but also at their output, doubling output range.
