    摘要： A circuit (10) for use e.g. in digital-to-analog converters, comprises a first transistor (M1) and a second transistor (M3) having respective control terminals coupled to a first bias voltage node (VB1) and a second bias voltage node (VB2) as well as a first electronic switch (M2). The current paths through the first (M1) and second (M3) transistor and the first electronic switch (M2) are cascaded in an output current line between a circuit output node (Iout) and ground (GND). A second (M4) and a third (M5) electronic switch are provided activatable to a conductive state to provide charge transfer current paths coupling the charge transfer node (Y).

    摘要： The present invention provides systems and methods that utilize inductive current steering to improve logic circuit performance by mitigating propagation delays associated with conventional transistor current steering. The system and methods employ RF transformers, wherein energizing primary windings induce current in associated secondary windings. In one aspect, a single clock bus is employed to induce the current, which is routed via respective ends of the secondary winding to emitter leads of the transistors. This current and voltage is 180 degrees out-of-phase such that one transistor is "on" while the other is "off," which generates a differential output. In another aspect, a differential clock signal is employed to induce the current in secondary windings and associated transistor emitters. Further, the systems and methods can be utilized to construct flip-flops and shift registers by coupling differential transistor pairs and driving these pairs with the transformer-based single-ended or differential clock.

    摘要： A driving circuit with low power dissipation is disclosed for at least one field effect transistor (F). A supplementary inductance (LN) is coupled to the inductance (LH) in the driving line of the field effect transistor (F) to feed back excess energy. The fed back energy may in particular be supplied to the gate driving electronic. The field effect transistor (F) driving power can thus be reduced.

    摘要： A differential switch (30) accepts a binary control signal (MSB) and its complement (which may be skewed with respect to the control signal) and latches both signals simultaneously. The latched output signals drive the control terminals of a differential switch pair (38) which connects one of two terminals to a third terminal, depending upon the state of the control terminals. The differential switch may optionally include an inverter (INV3) which complements the binary control signal, thus eliminating the need for external inversion of the control signal. The switch is particularly applicable for use in a digital to analog converter.

    摘要： An N-channel power MOSFET includes a storage capacitor and a pair of diodes connected between the gate and drain terminals, respectively, and the capacitor. Since either the drain or the gate of the MOSFET is always high, a charge is maintained on the storage capacitor as the MOSFET is switched on and off. The charge stored on the capacitor yields an output voltage which may be used to power a gate drive circuit or other components within or outside the MOSFET.
