parallel_rc_p2s - Convert Parallel RC Network into Equivalent Series RC Network

SYNOPSIS

[] = parallel_rc_p2s(Cp, Rp, Qp, freq, flag, Cs, Rs, Qs, Cp, Rp, Qp)

PARAMETERS

INPUT PARAMETERS

Cp : Parallel capacitance (Farads)
Rp : Parallel resistance (Ohms)
Qp : Parallel 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 series RC network from an input parallel RC network.

EXAMPLE

 // 10 pF
Cp=10e-12;
 // 5 kOhms
Rp=5e3;
 // This value will be replaced
Qp=100;
 // 100 MHz operation
f=100e6;
 // Use Rp (and calculate Qp)
flag=0;
[Cs, Rs, Qs, Cp, Rp, Qp] = parallel_rc_p2s(Cp, Rp,
  Qp, f, flag);
disp(sprintf('Equivalent series C = %g pF', Cs/1e-12));
disp(sprintf('Equivalent series R = %g Ohm', Rs));
disp(sprintf('Quality factor      =%g',Qs));
