A single electron transistor consisting of a conducting island coupled to two tunnel junctions and a gate capacitor is biased asymmetrically. The tunnel junctions have capacitances $C_1$, $C_2$ and resistances $R_1$, $R_2$. The gate capacitance is $C_g$ and the offset charge on the island is $Q_0$. Tunnel junction 1 is grounded and a bias voltage $V_b$ is applied to tunnel junction 2. A gate voltage $V_g$ is applied to the gate. The form below can be used to plot the current voltage characteristics for bias voltages at temperature $T$ from $V_b$(start) to $V_b$ (stop). $N$ is the number of points used in the plot. The equations that are used are described in Günther Lientschnig, Irek Weymann and Peter Hadley,
