A 10.7-MHz self-calibrated switched-capacitor-based multibit second-order bandpass ΣΔ modulator with on-chip switched buffer.

A 10.7-MHz self-calibrated switched-capacitor-based multibit second-order bandpass ΣΔ modulator with on-chip switched buffer.

A second-order multibit bandpass ΣΔ modulator (BPΣΔM) used for the digitizing of AM/FM radio broadcasting signals at a 10.7-MHz IF is presented. The BPΣΔM is realized with switched-capacitor (SC) techniques and operates with a sampling frequency of 37.05 MHz. The input impulse current, required by t...
