Peak Detector Circuit Using Op Amp. Open the circuit in the circuitlab editor and press f5 to run the time domain simulation. Dual limit comparator with lm709.
Dual limit comparator with lm709. Due to negative output diode d is reverse biased and acts as open circuit isolating op amp output and capacitor c. In this video the peak detector circuits have been explained.
Whenever the applied input voltage signal is greater than the threshold voltage of the diode the diode will get forward biased and acts as a closed switch.
4 peak voltage tester circuits using op amp and 723 precision peak voltage detector with a long memory time. In response to conflicting impedancies in peak detector. As we can see the circuit is comprised of 2 op amps. Its working principle is the same as the above circuit when a higher voltage pulse arises it stores it.
