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
