SYNOPSIS

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));
