Hi,

I'm currently simulating a Flipped Voltage Follower. I've ran a transient analysis (pulse wave) and the output seems to show large voltage spikes.
What could I do to remove this all together? or anything I could try adding to the circuit?

any help is appreciated. thanks!!

enhance the value of 10uf to100uf to remove the spikes.

Is the bottom symbol a current source? If it sees high impedance at any time, then it will try to overcome it by generating a high voltage.

As Brad noted, an idealized current source can be problematic in that circuit.
Better to simulate with the real current source that you will use (current mirror?).
