+In this simulation we are going to look at a single-transistor amplifier +in frequency domain to verify how it amplifies a sine waves. Compared to +the trans variant the only difference is +how we specify the transistor pinout and how the simulation setup is configured. + +
+Largely the same as trans variant. +
+
++ +
+This example demonstrates using spice/portmap to set the pinout: the +stock spice/pinnum attributes has been manually removed from Q1 terminals and +a portmap attribute, array type, added to the Q1 symbol. The portmap is: +
+{C->spice/pinnum=1}
+{B->spice/pinnum=2}
+{E->spice/pinnum=3}
+
+
+Since the attribute is called spice/portmap, it does not interfere with
+the normal portmap attribute (installed by devmap in our example) and it
+affects the spice workflow only.
+
+The simulation setup process is largely the same as in the
+base example of dc op point. The simulation
+setup in this example is called "ac characteristics".
+
+
Modifications
+
+This circuit needs two voltage sources, which are both added as modifications.
+The first one is a DC 5V source connected to net Vcc (and GND). The second
+acts as the small signal AC source for the AC analysis, this it has a an AC
+value (of 0.1 V); it is connected to net in (and GND).
+
+
+
Sim setup: output config
+
+(Same as in example 06_passive_ac )
+
+This simulation has two output configs, one for displaying the transfer
+(in decibel) and one for the phase (in radian). The reason for specify them
+in two separate output is the largely different y scale and unit.
+
+The first output uses ac (dec) for analysis. This will feed in 10
+different frequencies per decade and caputre the output. This also means
+the X axis, frequency, is logarithmic (common for frequency domain analysis).
+
+The property to plot is vdb(out), which is the "voltage decibel" of
+the network called out. Instead of the net name a component-port could be
+specified within vdb().
+
+The second output uses anlaysis previous, which means no new simulation
+is ran, but the data of the previous simulation is used. The presentation is
+also a plot of "out", but using the cph() function, which is the phase in
+radian.
