Its been a while I took a long hiatus due to not having a scope any longer, but I finally saved up and got myself one.
I was playing around with a precision rectifier (OPA350PA) and I came across something I don't understand.
Link to datasheet: OPA350 DATASHEET
What's going on with the positive cycle? It's somehow losing voltage somewhere. To make things more confusing for me I did it on paper and the diode is open (R.B) during the positive cycle so there's no current flowing thru the resistive network thus making all the voltage at each node the same as the input. Meaning Output should be equal to input.
Two case scenarios:
Case 1:
(Orange input / Green output)
Case 2:
