    摘要: In the present invention, a voltage level shifting circuit is disclosed. The voltage level shifting circuit comprises a first inventer and a second inverter with each inverter having a P-type MOS transistor and an N-type MOS transistor. Each of the inverters has an input port, an output port, a first voltage port and a second voltage port. The source of the P-type MOS transistor or N-type MOS transistor of each inverter is connected to the first voltage port. The voltage level shifting circuit also comprises two MOS transistors of the same conductivity type as the transistors of the inverter whose source is connected to the first voltage port. Each of the MOS transistors has a source, a drain and a gate with the drain connected to the first voltage port of each of the inverters. The sources of the first and second MOS transistors are connected together and to a high voltage level, such as V.sub.pp. Cross-coupling is provided by connecting the gate of the MOS transistor to the output port of the other inverter. The output is taken from the output port of the second inverter.

    摘要: A dual channel source measurement unit for reliability testing of electrical devices provides a voltage stress stimulus to a device under test and monitors degradation to the device under test caused by the stress simulator. The dual channel source measurement unit decouples the stress and monitor portions of the unit so that the requirements of each can be optimized. Deglitching and current clamp switches can be incorporated in the dual channel source measurement unit to prevent glitches in the switching circuitry and to limit or clamp current flow to or from the monitor and stress sources.
