Precision Rectifier: Get Answers to Your Questions

Click For Summary
The discussion centers on the operation of a precision rectifier and the relationship between output voltage (Vout) and the input voltage (E). Participants clarify that Vout equals E because the op-amp compensates for the diode forward voltage drop through negative feedback, effectively nullifying its impact on the output. The confusion arises from a lack of understanding of op-amp characteristics, particularly how they function in this circuit. The precision rectifier design allows for accurate rectification without the typical diode voltage drop affecting the output. Understanding op-amp behavior is crucial for grasping the precision rectifier's functionality.

hey,dude,i m confusing about the precision rectifier...why the Vout =E,my question is why the Vout=E - V(diode) ?why the Vdiode does not take into account when finding Vout?here the attachement of the precision circuit diagram..

The op-amp compensates for the diode drop as part of the negative feedback.
 
oic~~~~quite confusing about that because i haven't learn the characteristics of opamp.anyway.thx ya~
 
Thread 'I thought it was only Amazon that sold unsafe junk'
I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
