Hello,
We are using this inverter to achieve signal shaping, both the power rail is 3V, could you pls help review this circuit, and let me know if any suggestion.
thank you.

Hi Leo,
I tested this setup in my lab and got the following results:
With your configuration (SN74LVC1GU04 with 620k feedback and 1k input resistor).
You can see here that the input (green) is amplified, but only by about 3x.
I shorted out the 1k input resistor and got this result:
Here you can see that the output nearly reaches both rails, which is ideal for this wave-shaping circuit.
I would recommend removing the 1kohm input resistor, and then your circuit should work.
