  • Abstract
    A design technique for a double-delay based quadrature ΣΔ modulator is presented. The architecture uses a two-path scheme, which avoids mirror tones in the signal band and locks the intermediate frequency with the clock, thus avoiding the trimming requirement. The two-path architecture and time interleaving lead to an overall power reduction by a factor of 8.
