Publication number: 20140009129Abstract: A main reference value setting unit generates a voltage reference value DREF—V which represents a target level of a power supply voltage VDD. A digital calculation unit generates a main control value DOUT by digital calculation such that a digital voltage measurement value DM—V which represents the voltage level of the current power supply voltage VDD matches the voltage reference value DREF—V. A main D/A converter converts the main control value DOUT into an analog power supply signal SPS, and supplies the analog power supply signal SPS thus generated to a power supply terminal of a DUT via a power supply line. An auxiliary current source supplies an auxiliary current ISUB to the power supply terminal of the DUT via a sub-path that differs from the power supply line.Type: ApplicationFiled: June 21, 2013Publication date: January 9, 2014Applicant: ADVANTEST CORPORATIONInventors: Takahiko Shimizu, Katsuhiko Degawa

Publication number: 20120049893Abstract: A voltage source generates a power supply voltage VOUT stabilized such that it matches the voltage level that corresponds to a reference voltage VREF, and supplies the power supply voltage to a DUT. A current detection circuit generates a detection voltage Vm that corresponds to an output current IOUT that flows through the DUT. In the initial state, the reference voltage VREF generated by a reference voltage generating circuit is set to an initial voltage level that corresponds to an input voltage VIN. After the output current IOUT flows, the reference voltage transits to a first voltage level VL1 obtained by shifting the initial voltage level by a first voltage step that corresponds to the detection voltage Vm. Subsequently, the reference voltage VREF transits to a second voltage level VL2 obtained by shifting the initial voltage level by a second voltage step that corresponds to the detection voltage Vm.Type: ApplicationFiled: August 26, 2011Publication date: March 1, 2012Applicant: ADVANTEST CORPORATIONInventors: Satoshi Kodera, Takahiko Shimizu
