[Switched-capacitor filter]10K 100K 1MHz test fft for ?

like VCO's phase noise?


Thanks a lot !

like VCO's phase noise?

Switched-capacitor filter "flaws" and issues to test:
- noise spectral density, any high-frequency noise peaks?
- dc offset and drifts
- in-band gain inaccuracy
- large-signal distortion, near the positive rail, etc.
- distortion associated with output loading, if applicable
- phase-shift linearity (constant delay), if applicable
- stopband attenuation, if applicable

Thanks,
- Win
