Effect of frequency response mismatch in LPFs
The effect of single-channel LPF frequency mismatch on the frequency dependence of the ENOB.
- Example: 8-pole Butterworth, 5-channel system with 4 GHz -3 dB LPF bandwidth and no sources of noise
- Difficult to maintain better than 0.25% LPF frequency mismatch over 0oC < T < 70oC
