Precision Rectifier: Get Answers to Your Questions

Click For Summary
SUMMARY

The discussion centers on the operation of precision rectifiers, specifically addressing the output voltage (Vout) in relation to the diode forward voltage drop (Vdiode). It is established that Vout equals the input voltage (E) due to the op-amp's negative feedback mechanism, which compensates for the diode drop. This feedback allows the precision rectifier to effectively eliminate the impact of Vdiode on the output voltage, enabling accurate rectification even at low input voltages.

PREREQUISITES
  • Understanding of operational amplifier (op-amp) fundamentals
  • Knowledge of diode characteristics and behavior
  • Familiarity with negative feedback concepts in electronic circuits
  • Basic circuit analysis skills
NEXT STEPS
  • Study operational amplifier configurations and their applications
  • Learn about diode forward voltage drop and its implications in circuits
  • Explore negative feedback in op-amp circuits for improved performance
  • Investigate precision rectifier circuit designs and their use cases
USEFUL FOR

Electronics students, circuit designers, and engineers interested in understanding precision rectifiers and improving rectification accuracy in low-voltage applications.

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~
