    摘要: A circuit for controlling the switching operation of a transistor is described. A gate driver circuit is operably connected to a control electrode of the transistor and is configured to charge and discharge the control electrode to switch the transistor on and off, respectively, in accordance with a control signal. The charging and discharging of the control electrode is done such that the corresponding transitions in the load current and the output voltage are smooth with a defined slope. A controllable switch is connected to the control electrode such that, when the switch closes, the control electrode is quickly discharged via the switch thus quickly switching off the transistor. A control logic circuit is configured to close the controllable switch for switching off the transistor when at least one of a number of conditions holds true.

    摘要: A circuit configuration for mixing a differential desired signal with a differential local oscillator signal includes two difference amplifiers which are controllable on the input side by the desired signal and cross-coupled on the output side. Currents flowing through the difference amplifiers are switched by the components of the local oscillator signal in alternation. The circuit makes a lower supply voltage possible, given the presence of only two transistor levels.

    摘要: A frequency splitter circuit includes only two differential amplifiers. A clock input signal is supplied to clock signal inputs for activating the amplifiers. A respective signal of half the frequency of the clock input signal is derivable at main and auxiliary outputs. The differential amplifiers are cross-coupled. The frequency splitter circuit is operable with low supply voltage and provides high signal amplitudes at the output, high edge steepness, and low phase noise. The frequency splitter circuit can be utilized in high-frequency receivers, for example.
