function cj = junctioncap(vb, cj0, m, phi)
% analysis of junction capacitance;
% if vb is a vector with two values, an average capacitance over the range
% given by the voltages is given
% otherwise a vector of capacitances is returned
if (length(vb) == 2)
   keq = ((-phi^m)/((vb(2)-vb(1))*(1-m)))*((phi-vb(2))^(1-m)-(phi-vb(1))^(1-m));
   cj = cj0 * keq;;
else
   cj = cj0 ./ (1 - (vb/phi)).^m;
