Mex-Wcalc: parallel_rc_s2p

parallel_rc_s2p - Convert Series RC Network into Equivalent Parallel RC Network

SYNOPSIS

[] = parallel_rc_s2p(Cs, Rs, Qs, freq, flag, Cs, Rs, Qs, Cp, Rp, Qp)

PARAMETERS

INPUT PARAMETERS

  • Cs : Series capacitance (Farads)
  • Rs : Series resistance (Ohms)
  • Qs : Series quality factor
  • freq : Analysis frequency (Hertz)
  • flag : indicates if Qs or Rs should be used for the loss input
    • flag=0 : Qs will be calculated from Rs.
    • flag=1 : Rs will be calculated from Qs.
  • Cs : Series capacitance (Farads)
  • Rs : Series resistance (Ohms)
  • Qs : Series quality factor
  • Cp : Parallel capacitance (Farads)
  • Rp : Parallel resistance (Ohms)
  • Qp : Parallel quality factor

OUTPUT VALUES

    DESCRIPTION

    Function to calculate an equivalent parallel RC network from an input series RC network.

    EXAMPLE

     % 10 pF
    Cs=10e-12;
     % 0.5 Ohms
    Rs=0.5;
     % This value will be replaced
    Qs=100;
     % 100 MHz operation
    f=100e6;
     % Use Rs (and calculate Qs)
    flag=0;
    [Cs, Rs, Qs, Cp, Rp, Qp] = parallel_rc_s2p(Cs, Rs,
      Qs, f, flag);
    disp(sprintf('Equivalent parallel C = %g pF', Cp/1e-12));
    disp(sprintf('Equivalent parallel R = %g kOhm', Rp/1e3));
    disp(sprintf('Quality factor         =%g',Qp));
