Analysis of the Noise Performance<br />

The resolution of this detection system is a function of the noise generated by the circuit. It is<br />

therefore the major performance criterion of the device.<br />

The noise performance of the complete circuit strongly depends on the performance of the preamplifier.<br />

The analog memory port does not generate noise, it only shapes the noise generated<br />

by the amplifier.<br />

A number of transient noise simulations were performed on the complete circuit.<br />

Figure 21-45 shows the results of several transient simulation runs including noise sources, with<br />

different initial conditions and the RMS value of the noise at the amplifier output calculated<br />

from the different runs described above.<br />
