    • 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.

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.

    • A transmitter (4) for a controlled-shape switched signal on a communication line (1) comprises a signal generator including a capacitor (19) producing the switched signal to be applied to the line. The capacitor is charged by a charging current (I c ) in response to an input signal (TX) so as to define an edge of the switched signal. The charging means (24, 25) comprises a feedback loop responsive to the capacitor voltage (V O ) for generating a feedback current (I E ) having a continuous magnitude that is a progressive function of the capacitor voltage, the charging current (I c ) being a function of the feedback current (I E ). Resistors (R; R 1 , R 2 ) define an RC circuit with the capacitor (19) enabling the time constant of the feedback current to be controlled.
      Preferably, the feedback loop generates first and second feedback voltages (V H , V L ) one of which is a rising function of the capacitor voltage (V O ) and the other is a falling function of the capacitor voltage (V O ). The feedback current (I E ) is generated first as a function of one of the feedback voltages (V H , V L ) and subsequently as a function of the other of the feedback voltages, so that the rate of change of the feedback current (I E ) increases with time while the one of the feedback voltages is selected and decreases with time while the other of the feedback voltages is selected.
      Preferably, the rate of change of the feedback current (I E ) is a function of the capacitor voltage (V O ) such that the capacitor voltage varies substantially as an exponential function of time, at least for a part of the edge of the switched signal (40, 42, 44, 46) and may be a linear function of time for another part (41, 43, 45) so as to approximate closely a sinusoidal half cycle with few harmonics.
