Design of a 70-MHz IF 10-MHz bandwidth bandpass ΣΔ modulator for WCDMA applications
In this paper we present a MASH bandpass Σ∆ modulator for WCDMA applications. The signal bandwidth of the proposed modulator is 10 MHz, centered around an intermediate frequency (IF) of 70 MHz. Each Σ∆ modulator of the MASH structure is based on a two-path architecture, which allow us to obtain the desired in-band noise shaping zeros and reduce the power consumption. The Σ∆ modulator is impleme...
متن کاملNoise-Coupled Image Rejection Architecture of Complex Bandpass DeltaSigmaAD Modulator
This paper proposes a new realization technique of image rejection function by noise-coupling architecture, which is used for a complex bandpass ΔΣAD modulator. The complex bandpass ΔΣAD modulator processes just input I and Q signals, not image signals, and the AD conversion can be realized with low power dissipation. It realizes an asymmetric noise-shaped spectra, which is desirable for such l...
متن کاملA Voltage-Mode Switched-Capacitor Bandpass ∆Σ Modulator
A novel fourth-order voltage-mode switched-capacitor bandpass ∆Σ 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 ∆Σ data converters. It is therefore suitable for high-speed communications applications.
متن کاملGain and offset mismatch calibration in multi-path sigma-delta modulators
In this paper we propose a digital background adaptive calibration technique for correcting offset and gain mismatches in multi-path sigma-delta (ZA) modulators. The proposed technique allows us to cancel the spurious tones introduced by offset and gain mismatches among the paths only by processing the digital output, without interfering with the operation of the modulator. This solution is als...
متن کاملA Complex Bandpass ∆Σ Converter for Digital Radio
A new architecture is proposed for a singlechip digital radio receiver. This architecture has several advantages over the direct conversion architecture that has been gaining interest for use in single-chip designs. A non-zero quadrature IF reduces the image problem and eliminates concerns about self-EMI and 1/f noise. A “complex” bandpass filter embedded in a delta-sigma (∆Σ) loop allows the A...
