ABSTRACT:
A switchable current source circuit includes a current mirror configuration having a control stage and an output stage. The control stage has a voltage output and a current input and furnishes a control voltage at the voltage output as a function of a control current impressed at the current input. The output stage has a control input connected to the voltage output of the control stage and a control path with two terminals. One of the terminals forms a current output of the current source circuit. An electronic switch has one terminal connected to the other of the terminals of the control path of the output stage, another terminal being connected to a supply potential terminal, and a control input. The current source circuit is switched on and off as a function of triggering the control input of the electronic switch. A capacitor connects the control input of the electronic switch to the control input of the output stage of the current mirror configuration. A bipolar current source configuration includes at least two of the switchable current source circuits. A phase detector has an output stage including at least one of the bipolar current source configurations.
