摘要：A phase-controllable oscillator consists of a capacitance and an apparatus forcharging and an apparatus for discharging the capacitance. In addition, feedback isprovided for activating the charging and discharging apparatus in dependence on theoscillator signal. An amplifier for amplifying the capacitance voltage can be phase-controlled by providing the amplifier with a control input for adjusting the phasedifference between a zero-crossing of an amplifier output signal on the one hand and areference phase in the oscillator signal on the other hand. In order to maintain the dutycycle, a switching apparatus is provided for reversing the polarity of the control inputunder the control of the oscillator signal.
