- Abstract:
- A novel fourth-order voltage-mode switched-capacitor bandpass ΔΣ modulator, using direct-charge-transfer pseudo-N-path resonators, is described. This modulator is insensitive to component mismatches and finite opamp bandwidth, and is also less sensitive to finite opamp gain than previous bandpass ΔΣ data converters. It is therefore suitable for high-speed communications applications.
