phase shifter using OP37

Question asked by hasmukh789 on Mar 28, 2017

hi

i am trying to develop a phase shifter using integrator concept. working Range 10KHz to 1MHz.

considering High frequency i am using OP37 which has high Gain bandwidth and slew rate.

i am Facing a problem with instability in output signal.

Problem is Facing 20 MHz signal in input and output. circuit is loading input(Function generator output)

Here i attached Circuit Diagram and output results.

hope for valuable comments

 

thanks
