Claim 9:
10. A method for measuring a quiescent current in a boost switching voltage regulator, the method comprising:
generating a mathematical model of a circuit design associated with the boost switching voltage regulator, the mathematical model comprising measurable parameters to describe an average switching current and internal operational currents associated with a power switch of the boost switching voltage regulator;
fabricating a circuit comprising the boost switching voltage regulator based on the circuit design, the fabricated circuit comprising the power switch and conductive inputs/outputs (I/O);
coupling the conductive I/O of the fabricated circuit to a circuit test fixture;
providing electrical signals to the conductive I/O via the circuit test fixture;
measuring the measurable parameters in response to the electrical signals;
applying the measurable parameters to the mathematical model to calculate the average switching current; and
calculating the quiescent current based on the average switching current and the internal operational currents associated with the mathematical model.
