    • The circuit (Fig. 1) rapidly charges and discharges a load capacitor by sensing the direction of transients at an internal node (12) of the circuit which is selectively isolated from a capacitive output node (26) to produce significant load current during upward transients. In an embodiment of the invention, the circuit includes a driver device (10) and first (18), second (24) and third (30) field effect transistors. The first transistor (18) is connected between a voltage supply terminal (20) and the driver device (10) forming an internal node (12) and acts as a current source pulling up the internal node. The second transistor (18) is connected between the internal node (12) and an output node (26) and is arranged to selectively isolate the internal node from the output node, with isolation increasing during a positive transient to allow maximum drive to the third transistor connected between the voltage supply terminal and the output node to produce increased output current. The second transistor (26) is also arranged to minimize the isolation between the internal and output nodes (12, 26) during negative transients to rapidly discharge the output node.

    • The circuit comprises an E-mode transistor (E3) with gate-source junction, a D-mode transistor (D) with gate-source junction, a component generating a voltage drop (E1, E2) between the source (4) of the D-mode transistor and the drain (2) of the E-mode transistor, and a connection (7) between the drain (2) of the E-mode transistor and the gate (6) of the D-mode transistor. The gate (3) of the E-mode transistor is provided for an input signal (IN), and the drain (2) of the E-mode transistor is provided for an output signal (OUT). The circuit enables the operation of logic circuitry in GaAs technology with only low currents flowing.
