ABSTRACT:
GaAs digital electronics uses mainly depletion mode MESFET technology. In typical circuits, negative voltage logic input signals are required while the output voltage is positive. To connect gates, level shifters are needed to shift the positive voltage output signals such that they become suitable for the input to the next gate. A capacitor is used which performs the level shifting. As the charge leaks off the capacitor, the voltage level has to be readjusted periodically, leading to a "dynamic" circuit. A method for self-biasing of the capacitor for readjustment of the voltage level is taught.
