    摘要: A level shifting circuit which can be implemented as part of a bipolar ECL integrated circuit, provides reliable switching and level shifted output suitable for driving a low voltage CMOS integrated circuit. The circuit includes a level shifting circuit which is connected to trigger a high gain positive feedback bootstrap circuit to reliably ensure switching even under poor signal conditions. An output taken from one of the switched pair is allowed to go to V.sub.CC, 0 volts, or is clamped by a clamping circuit to -3.3 volts, representing the two output states suitable for driving inverted rail CMOS circuitry.

    摘要: The present invention provides an ECL EPROM circuit which uses a MOS memory cell. The invention includes a technique for programming the memory cell using MOS voltage levels, and also includes circuitry for reading the memory cell at ECL voltage levels. Thus, the programming and reading paths are split to give the ease of programming and the reprogrammability of MOS EPROM devices combined with the reading speed of PROM devices using ECL voltage levels. In one embodiment, two parallel paths are provided to a memory cell to enable it to separately receive reading and writing (programming) signals. The reading path employs ECL components for reading the cell, while the writing path contains MOS components for programming and verifying the cell. The memory cell itself contains a MOS memory element, an ECL pass element, and a sense element coupling the MOS memory element to the ECL pass element. The MOS memory element is coupled to the programming (writing) path, and the ECL pass element is coupled to the read path with a bipolar output transistor.

    摘要: The present invention provides a voltage reference level using a bipolar output transistor to provide a reference voltage on a reference output line. A control circuit is used for varying the current to the base of the output transistor in response to the load on the reference output line. In addition, the control circuit provides the reference level to the output transistor. The MOS control circuit and the bipolar output transistor are fabricated on the same chip using a BICMOS process. The voltage reference provided by the control circuit is derived from a voltage level provided by a resistor coupled between the positive voltage supply and a current source.
