A conventional test setup for measuring the current / voltage characteristics of a low-power integrated circuit (IC) requires a variety of basic instruments. The setup includes multiple power supplies to supply the required voltage to various test ports with different voltage requirements and digital multimeters (DMMs) for measuring voltage and current. Some test cases require pulse generators for simulating signals and digitizers for capturing signals in the time domain.
Use a source measure unit (SMU) as a power supply and an ammeter, voltmeter, and digitizer to perform multi-channel synchronous current / voltage (IV) measurements. Set instrument self-calibration and accurate measurement range before any sleep current measurements, especially for ICs with precision levels below milliamps (mA). For accurate dynamic measurements, the SMU’s sampling rate must be fast enough to capture signals during the transition from sleep to active state.
