If your op-amp circuit is not switching correctly or behaving unpredictably, the issue is usually related to biasing, signal levels, or incorrect configuration.

Many comparator and signal detection circuits fail because of small design mistakes that are not obvious at first.

I help you troubleshoot op-amp circuits and identify why they are not working as expected.

This includes analyzing input and output behavior, verifying operating conditions, and checking if the circuit is within proper voltage and signal limits.

Whether youre using LM358, LM393, or similar devices, I focus on finding the root cause and correcting the circuit behavior.

The goal is to make your circuit switch cleanly, respond correctly, and operate reliably under real conditions.

If your circuit is unstable, stuck, or not responding to signals, you can share your design and Ill guide you before we begin.
