Abstract: One example includes a method for measuring a quiescent current in a switching voltage regulator. The method includes generating a mathematical model of a circuit design associated with the switching voltage regulator. The mathematical model includes measurable parameters to describe a switching current of a power switch of the switching voltage regulator. The method also includes fabricating a circuit comprising the switching voltage regulator based on the circuit design. The fabricated circuit includes the power switch and conductive I/O. The method also includes coupling the conductive I/O of the fabricated circuit to a circuit test fixture and providing electrical signals to the conductive I/O via the circuit test fixture. The method also includes measuring the measurable parameters in response to the electrical signals and applying the measurable parameters to the mathematical model to calculate the switching current. The method further includes calculating the quiescent current based on the switching current.

Abstract: In described examples, a circuit includes a first current mirror circuit. The first current mirror circuit is coupled to a power input terminal. A first stage is coupled to the first current mirror circuit, and a second stage is coupled to the first stage and to the first current mirror circuit. An amplifier is coupled to the first and second stages. The amplifier has first and second input terminals. The first input terminal is coupled to the first stage, and the second input terminal is coupled to the second stage. A second current mirror circuit is coupled to the first stage, the second stage and the amplifier.
