Abstract:
A fully differential delta sigma modulator is provided. The fully differential delta sigma modulator has an integrator in which a comparator replaces an operational amplifier for decreasing power consumption. The integrator extends to a fully differential implementation with the addition of a common-mode feedback circuit for improving equivalent input and signal-to-noise ratio.
