SWITCHING BETWEEN DEEP-LEVEL TRANSIENT SPECTROSCOPY AND FEEDBACK CHARGE CAPACITANCE MODES IN A VERSATILE TIME-DOMAIN SPECTROMETER

Software-supported switching between the deep-level transient spectros copy (DLTS) and feedback charge method (FCM) operation modes of a vers atile time-domain spectrometer, while using identical circuitry, is de monstrated. No additional correction of the output signal for integrat ed leakage current is needed. The timing scheme design is discussed in more detail with reference to a practical example. The interval of ac hievable rate windows is not affected by the switching between the DLT S and FCM modes of the instrument. A few illustrative examples of DLTS and C - V plots are included.
