Speed-up charge pump and phase-locked loop and method for operating the same

A method for operating an electronic circuit, comprising:

• providing a speed-up charge pump, comprising:
• providing a first charge pump, receiving an up signal and a down signal in digital form to produce a first voltage control signal at an output node;
• providing at least one speed-up phase detector, comprising:
• providing a first circuit path to receive the up signal and delay the up signal by a predetermined delay as a delay up signal and operate the up signal and the delay up signal by AND logic into an auxiliary up signal unrelated to the down signal;
• and
• providing a second circuit path to receive the down signal and delay the down signal by the predetermined delay as a delay down signal and operate the down signal and the delay down signal by AND logic into an auxiliary down signal unrelated to the up signal;
• and
• providing at least one second charge pump, respectively receiving the auxiliary up and down signals to produce a second voltage control signal also at the output node.
