Using 3 minute search processes, the device and the method of acquiring device signal value

摘要

Being the device in order to using for the acquisition of value from the device, the standard high signal (Voh) and the device signal (DUT signal 25) 1st it receives the comparator (19) being, the 1st output signal which shows whether the device signal (DUT signal 25) the standard high signal (Voh) being higher, or it is low (27) it offers, the 1st comparator and the standard low signal (VoI) and the device signal (DUT signal 25) the 2nd comparator which is received (20) being, the device signal (DUT signal 25) standardThe 2nd output signal which shows whether the low signal (VoI) being higher, or it is low (29) it offers, it has with the 2nd comparator. The standard high signal (Voh) and the standard low signal (VoI) one side is adjusted at least in the particular device the 1st output signal (27) and the 2nd output signal (29) of on the basis, at the same time, the standard high signal (Voh) with the standard low signal (VoI) with difference (21) value is output to the case where specified standard is satisfied, the circuit (computer 14) being, value has been based on difference, also the circuit has.
