opamp Precision Rectifier

Hi friends,
this is a simple opamp precision rectifier. Very useful in rectifying or making bipolar signals unipolar, specially in small signals where we cannot afford to have that 0.7v drop across the normal diode bridge rectifier.
The circuit shown here gives rectified output going only in the negative direction, as my application required it that way. But if you want rectified positive output, just reverse the direction of both the diodes and you'll get it!

Is this a full wave rectifier ?

CC Dharmani said...

Yup!

Chad said...

Can it be altered to a half wave?

CC Dharmani said...

Yes, remove the vertical diode, put the horizontal diode at 1st opamp output terminal, and connect the feedback resistor between pin2 and the other terminal of the diode. Remove the second opamp & remaining parts.

nitesh said...

Can we also amplify the signal in the same circuit?

Wow, the concept of design with microcontrollers is truly fascinating! It's amazing how these tiny electronic devices have revolutionized the world by enabling us to create innovative, intelligent systems. The possibilities seem endless.
From industrial automation to wearable technology, microcontrollers have found their way into a wide range of applications. Designing with microcontrollers opens up doors to endless creativity and problem-solving. It allows us to build intelligent robots, control systems, and even interactive art installations.
One of the things that I find most exciting about design with microcontrollers is the opportunity to integrate them into everyday life. Imagine having a refrigerator that can automatically order groceries when you run out of food, or a home security system that can detect intruders and send alerts to your phone – all made possible by the power of microcontrollers.
The design possibilities are truly limitless when it comes to working with microcontrollers. I can't wait to see what the future holds for this technology and how it will continue to shape our world.

An essential circuit in signal processing is the precision rectifier, which employs operational amplifiers (op-amps) to accurately rectify alternating current signals. With its low distortion and little voltage drop, this design excels in precision, which is important for applications that require exact rectification. Its excellent accuracy in handling low-level signals makes it useful in measuring and instrumentation systems. Because of the op-amp's special design, performance is improved and reverse recovery time is reduced, leading to effective rectification. Its dependability in preserving signal integrity is valued by engineers and hobbyists, making it a crucial part of electronic circuits where accurate rectification is essential.
