  • Apparatus and method for emulating a component in a circuit
    Patent number: 7365953
    Abstract: A circuit and method for emulating a component in a circuit are shown that control a current controlled oscillator with a first current that is proportional to a square of a load current of the component and also charge and discharge a high precision capacitor using the current controlled oscillator. The oscillations of the current controlled oscillator are counted to obtain a count value, which is transformed to a transformed current signal using a predetermined transfer function. The transformed current signal is subtracted from the first current that controls the current controlled oscillator. The transformed current signal is subtracted from a second current that is proportional to a square of the load current to determine whether the count value is incremented or decremented responsive to the oscillations of the current controlled oscillator.
