  text: A tunable fourth-order bandpass ΔΣ modulator (BDSM) designed and fabricated
    in 0.25μm SiGe BiCMOS technology is presented. The designed modulator relaxes
    switching conditions for the amplification stage of the switch-mode power amplifier
    in comparison to the BDSM architecture. The BDSM is clocked at 5 GHz, while the
    notch frequency can be tuned in a range of 2.1-2.2 GHz. The modulator achieves
    46.6-dB signal-to-noise and distortion ratio in 10-MHz bandwidth for a sine-wave
    input at 2.2 GHz consuming 330 mW from a 3-V supply. The BDSM was also tested
    with a single-channel WCDMA signal. It has demonstrated 42.2-dBc adjacent channel
    leakage ratio at 5-MHz offset and less than 2.1% error vector magnitude over the
    tuning range.
