Method and circuits for charge pump devices of phase-locked loops

A method to operate a charge pump comprising a p-channel source current network that includes more than one p-channel transistors and a p-channel current switch, and a n-channel sink current network that includes more than one n-channel transistors and a n-channel current switch, the method comprising:

• receiving, at the p-channel source current network, one or more p-bias inputs;
• receiving, at the n-channel sink current network, one or more n-bias inputs;
• establishing a baseline current that flows from a first p-channel transistor of the more than one p-channel transistors in the p-channel source current network and sinks to a first n-channel transistor of the more than one n-channel transistors in the n-channel sink current network, wherein the baseline current bypasses an output line;
• and
• generating a voltage output on the output line by:
• in response to the p-channel current switch being activated, drawing a first increment current from the first p-channel transistor, wherein the first increment current flows (i) through the p-channel current switch to the output line of the charge pump, and (ii) in parallel with respect to the baseline current, and wherein the first increment current is smaller than the baseline current that is present continuously both before and after the p-channel current switch is activated;
• and
• in response to the n-channel current switch being activated, drawing a second increment current from the output line of the charge pump, wherein the second increment current flows (i) through the n-channel current switch to the first n-channel transistor, and (ii) in parallel with respect to the baseline current, and wherein the second increment current is smaller than the baseline current that is present continuously both before and after the n-channel current switch is activated.
