getting error on negative clipping

[bhuvaneshnick]

i am getting 0.7 error on negative clipping.Is there any possible modification that we can make to the below circuit to eliminate that error 0.7v.

The waveform at the output is normal.
The negative is not clipping, instead the positive is normally clipping.

sorry the positive is clipping but not normally.There is 0.7 drop by the diode

That is how the circuit works.
A forward biased silicon diode limits the voltage to about 0.7V across it at your fairly low current. When the current is much higher then the diode limits the voltage to about 1V.

You can add an opamp circuit to limit the rectifier error to almost nothing but the output current is low. This opamp does not show its positive and negative power supply. Reverse the diodes for a negative output voltage.View attachment 42119

ohh,clear somewhat thanks
