A 2.2-mW CMOS bandpass continuous-time multibit Δ-Σ ADC with 68 dB of dynamic range and 1-MHz bandwidth for wireless applications.

A 2.2-mW CMOS bandpass continuous-time multibit Δ-Σ ADC with 68 dB of dynamic range and 1-MHz bandwidth for wireless applications.

A delta-sigma (ΔΣ) analog-to-digital converter featuring 68-dB dynamic range and 64-dB signal-to-noise ratio in a 1-MHz bandwidth centered at an intermediate frequency of 2 MHz with a 48-MHz sample rate is reported. A second-order continuous-time modulator employing 4-bit quantization is used to ach...
