| Keywords: | BandPass Sigma-Delta Idle Tones |
| Publisher: | Institute of Electrical and Electronics Engineers |
| Description: | Ths paper analyses the tonal behaviour of the quantization noise in 2nd-order bandpass SD modulators. The analysis previously performed for lowpass modulators is extended to the bandpass case. As a result, closed-form expressions for the frequency of the idle tones are derived for different locations of the signal
center frequency. The analytical results are validated through measurements from a silicon prototype realized using fully differential
switched-current circuits in a standard 0.8μm CMOS technology. This work has been supported by the Spanish CICYT Project TIC 97-0580. Peer reviewed |
