Thanks for following #Long Range weather station

Several years ago, I designed a bipolar opamp, but only in simulation. I was surprised that the transconductance of a MOSFET is large enough.

I like you professional attempt and presentation, in particular the testing device.

Thank you for liking my #CMOS Homemade Operational Amplifier! I have now added comparative data to the article with my previous bipolar transistor version of the project, the OPM-01.
