Precision Rectifier
What is Precision Rectifier : It is a very small electronic circuit that is usually implemented by using an operational amplifier. A precision rectifier is used to precisely convert small AC signals into DC signals and without suffering from the kinds of voltage drop problems present in diode rectifiers. In technical terms, this circuit "rectifies" the signal by passing through only those parts of the AC waveform positive or negative and is effective for giving a clean smooth DC output even from low-level voltage inputs. For those applications of signal processing based on detection and measuring proper low-level signals in application like audio, instrumentation circuits, or sensor circuits, Precision rectifiers are most famous. Types of Precision Rectifier : There are two main types of precision rectifiers using operational amplifiers: Half-Wave Precision Rectifier This circuit only lets one half of the input AC waveform pass through which is either positive or negative to ...
