In this case, a linear voltage-controlled voltage source (E1) with a voltage gain of 20 has been used. The input and output nodes are 1 and 3, respectively. <table><tr><td> [[Image:Amp circ.png|thumb|left|420px|The schematic of the amplifier circuit in RF.Spice A/D.]] </td></tr></table> The same Netlist can be written using a B-type nonlinear dependent source as follows:
