Stephan Henzler Mixed-Signal-Electronics 2012/13<br />

Very sensitive to waveform<br />

and settling, limits linearity<br />

of modulator<br />

Filter transfer function<br />

depends on RC constants,<br />

i.e. very sensitive to<br />

variations<br />

Noise generation Switching generates noise Reduced supply and ground<br />
