FPGA are great for signals processing, but many signals we want to process start out as an analogue waveform. My latest Hackster project looks at how we can design analogue front ends which can be used with ADCs and FPGAs to give very accurate results. This approach can be very important for industrial, defence, space applications etc. https://lnkd.in/e4-iKhas

I read that, wondered what the difference between an FPGA sandwiched between an ADC and a DAC, verses a DSP is; and then remembered the much rarer chip with entirely analogue components in, so you can stay in the analogue domain. Possibly/probably using OpAmps instead of LUTs.

Digitization! I’ve had luck digitizing pluses at 40Msps for flow cytometry before. Technology has probably matured a bit since I did that work….
Fantastic project, Adam. You did a great job breaking down the tradeoffs in amplifier selection and signal conditioning. It’s a challenge we regularly help teams navigate—especially in aerospace and medical applications where accuracy and stability are everything. Analog front-end design might not get as much attention as digital logic, but it’s often the difference between a system that just works and one that performs with confidence.
