    Hi everyone ,

    Am using full wave precision rectifier using op amp for my application.

    I got output [​IMG] as shown in fig...

    How to get full DC voltage from this of course i put capacitor after op amp its not producing the desired output.

    When including the diode after op amp i got the full dc output but the output voltage is less than 0.7V due to diode voltage drop.

    So pl help me in this regards.
