Hi Steve,
Thanks for reminding me of 8052.com user space.
I have uploaded three gif files.
1. Here is my existing rectification circuit consisting of two half wave rectifiers built around TL084.


2. I have found this circuit on one of the web pages and I am not much satisfied with the performance. The problem is this circuit's rectified output is not symmetrical one half cycle looks bigger than the other on scope.


3. This circuit I found in one of the Burr-Brown application note document. This showed pretty good results.


I want your comments and suggestions given my application requirements. Which circuit I should use for better reliability and accuracy.

Regards,
Prahlad Purohit
