Abstract: front page image
(EN)A main power source (10) supplies a power supply voltage Vdd to a power supply terminal (102) of a DUT (100). A control pattern generation section (22) generates a control pattern CNT including a pulse train. A compensation circuit (20) intermittently injects a compensation current Icmp into the power supply terminal (102) of the DUT (100) from a path different from that of the main power source (10) according to the control pattern CNT. A switch (20b) is provided between an output terminal of a voltage source (20a) and the power supply terminal (102) of the DUT (100) and turned on and off according to the control pattern CNT.
(FR)Selon l'invention, une source d'alimentation principale (10) délivre une tension d'alimentation Vdd à une borne d'alimentation (102) d'un dispositif testé (100). Une section de génération de motif de commande (22) génère un motif de commande CNT comprenant un train d'impulsions. Un circuit de compensation (20) injecte de manière intermittente un courant de compensation Icmp dans la borne d'alimentation (102) du dispositif testé (100) à partir d'un trajet différent de celui de la source d'alimentation principale (10) selon le motif de commande CNT. Un commutateur (20b) est disposé entre une borne de sortie d'une source de tension (20a) et la borne d'alimentation (102) du dispositif testé (100) et allumé et éteint selon le motif de commande CNT.
(JA) メイン電源10は、DUT100の電源端子102に電源電圧Vddを供給する。制御パターン生成部22は、パルス列を含む制御パターンCNTを生成する。補償回路20は、制御パターンCNTに応じて間欠的に、メイン電源10とは別の経路からDUT100の電源端子102に補償電流Icmpを注入する。スイッチ20bは電圧源20aの出力端子とDUT100の電源端子102の間に設けられ、制御パターンCNTに応じてオン、オフが切り換えられる。
