PROGRAMMABLE GAIN TRANS-IMPEDANCE AMPLIFIER OVERLOAD RECOVERY CIRCUIT

摘要

Embodiments of an apparatus for measuring the leakage current of capacitive components is taught. One embodiment includes a first stage amplifier configured to receive an input from a serially-connected capacitive component at an inverting input and a feedback resistor in a feedback path of the first stage amplifier. A resistance value of the feedback resistor is programmable based on an expected value of the leakage current and a corresponding voltage output.
