Low noise transmission of output data from a delta-sigma modulator |
摘要 |
The output gates of a delta-sigma modulator can generate i(t) transient signal in the power supply lines of a delta-sigma modulator. These i(t) spikes, which would otherwise produce non-linearities which can be coupled into the frequency band of interest of the modulator, are made to be linear by using return-to-zero data encoding and by providing multi-bit outputs to the delta-sigma modulator in which the output states all have equal numbers of logic ones at the output lines for each of the output states.
