| Keywords: | BandPass Sigma-Delta Converters Idle tones |
| Description: | This paper analyses the tonal behaviour of the
quantization noise in second-order bandpass ΣΔ modulators. The analysis performed for lowpass modulators is extended to the bandpass case. As a result, closed form expressions for the frequency of idle tones are derived for different cases regarding the signal center
frequency position. All these results have been validated by measurements from a silicon prototype using fully differential switched-current circuits implemented in a standard 0.8μm CMOS technology. This work has been supported by the Spanish CICYT Project TIC 97-0580. Peer reviewed |
