摘要： Provided is a pulse generator that generates a pulse signal with a preferred waveform and offers increased isolation for a period of time when the pulse signal is not output.
A pulse generator 100 allows a high-frequency oscillator 101 to output a high frequency signal and allows an amplifier 102 to amplify and output the signal. The amplifier 102 amplifies the high frequency signal from the high-frequency oscillator 101 and outputs the signal only for a period of time when its drive power is supplied by a drive circuit 110. The waveform of the drive power, supplied from the drive circuit 110 to the amplifier 102, is controlled by a waveform control unit 120 such that the high frequency signal amplified by the amplifier 102 becomes an ultra-wideband pulse signal.

摘要： Apparatus and methods for quadrature clock signal generation are provided. In certain implementations, an apparatus includes an invertible sine shaping filter configured to receive an in-phase clock signal, a quadrature-phase clock signal, and an inversion control signal. The invertible sine-shaping filter is further configured to filter the in-phase and quadrature-phase clock signals to generate sinusoidal in-phase and quadrature-phase clock signals. The invertible sine-shaping filter is further configured to selectively invert one or both of the in-phase and quadrature-phase clock signals based on an inversion control signal. The apparatus further includes a phase interpolator configured to generate an interpolated clock signal based on a weighted sum of the selectively inverted sinusoidal in-phase clock signal and the quadrature-phase sinusoidal clock signal. The in-phase clock signal and the quadrature-phase clock signal have a quadrature-phase relationship.

摘要： A transmitter (4) for a controlled-shape switched signal on a communication line (1) comprises a signal generator including a capacitor (19) and a feedback loop responsive to a voltage across the capacitor (19) and to an input signal (TX) for supplying a shaped current ( I S ) for charging the capacitor (19) so as to define an edge of the switched signal. Signal producing means (9, 21) in the signal generator is responsive to the capacitor voltage for applying the controlled-shape switched signal to the line. The signal generator includes an amplifier (49) having an input terminal and an output terminal across which the capacitor means (19) is connected and at which it generates an amplifier output voltage ( V O ).
The feedback loop is arranged to maintain a minimum value of the shaped current ( I S ) at least in steady state conditions of the input signal (TX). The signal generator comprises first and second current diversion means (52, 53) operative at least in the steady state conditions in response to relative magnitudes of the amplifier output voltage ( V O ) and first and second limit voltages respectively for controlling supply of charging current ( I c ) to the amplifier and the capacitor (19) so as to tend to reduce charging and discharging of the capacitor means (19) in the steady state conditions and to maintain a steady state magnitude of the amplifier output voltage ( V O ) even against fluctuations induced by electromagnetic perturbations on the communication line.
