A plurality of MESFET input devices each have their gate electrode coupled to one input of the majority logic gate.

The voltage level at the drain at each of the input devices changes from a logical "0" to a logical "1" state depending upon the number of inputs which are at a logical "1" level. The drain voltage is then level shifted down. The high logic level output voltage is clamped to ground by means of two Schottky diodes the first of which has a cathode coupled to ground and an anode coupled to the anode of the second diode, the cathode of the second diode being coupled to the output of the circuit.

    • A voltage level translator circuit converts an input signal referenced between first and second operating potentials to an output signal referenced between second and third operating potentials. The input signal is level shifted through cascoded transistors and latched by series inverters to drive upper cascoded transistors in the output stage. The input signal is delayed before driving lower cascoded transistors in the output stage. The output stage transistors are cascoded in a similar manner as the level shifting section. The logic state of the input signal determines whether the upper cascoded transistors or the lower cascoded transistors in the output stage are activated to set the logic state of the output signal of the voltage level translator circuit. Additional cascoded transistors may be stacked to extend the range of voltage translation. The voltage level translator circuit is applicable to sub-micron technology.

    • A bipolar complementary metal oxide semiconductor (BICMOS) sense circuit for sensing data on read data lines during a read cycle of a memory comprises a load portion and a sense amplifier portion. In one form, the load portion couples true and complement read data lines to a first voltage in response to a start of a read cycle. When the true and complement read data lines exceed a predetermined voltage, the sense amplifier is enabled. The load portion becomes inactive when the voltage on the read data lines reaches approximately the first voltage. Then a selected memory cell provides a differential voltage on a bit line pair, which is coupled to the read data lines, indicating the contents of the selected memory cell. The sense amplifier provides a differential current onto a corresponding read global data line pair in response to the differential voltage. At the termination of the read cycle, the load portion becomes active again and couples the read data lines to a second voltage to disable the sense amplifier. The predetermined voltage is between the first voltage and the second voltage. The circuit increases the speed of the sensing function over a CMOS design, while keeping power consumption to a minimum. In another form, the sense circuit generates a read sense voltage that is substantially independent of non-tracking process variations between P-channel and N-channel field-effect transistors.
