Hi all,
I am experimenting with an enveloping circuit (precision full-wave rectifier) which I found here
When simulating this and increasing the input peak-to-peak to 4.5V (supply is 5V and the op amp has a rail-to-rail input output), I am getting a clamped rectifier negative cycle as evident from the snapshot below.
I tried various diodes, resistance values, op-amps, but this configuration is the best I can get.
Is there a way to prevent this from happening?
