Hi Kai,
The circuit that you have posted is really great and I want to first understand it completely before I use it. The above circuit is very much simillar to precision rectifiers I have seen in "National" Application Notes but with some differences. I will be very greatfull If you can please tell me the significance of the components encircled red in the following figure. I have never seen these 33pF capacitors and those two diodes on inverting terminal. ![]() Apart from the above stuff. In "National" Application notes They usually refer the resistor values as R & R/2 as shown in red in following figure. And in some app notes these values are 20K [R] and 10K [R/2]. But in your circuit you are using three different resitor values viz. 20K 22K & 11K. I couldn't understand the significance of using 20K why it is not 22K? ![]() Kai, I am sure these differences are certainly for better performance Please tell me what is the advantage of using these things. Thanks& Regards, Prahlad Purohit |
