Classification: CPC H | IPC H

Claim 3:
4. The PLL of claim 1, wherein the plurality of switchable voltage clamps is configured to the voltage transients in the ABC current DAC by:
receiving the at least one ABC code;
determining whether at least one ABC current mirror DAC branch is turned on based on the received at least one ABC code; and
perform one of,
providing an alternate current path for the at least one ABC current mirror DAC branch by maintaining a drain voltage of the at least one ABC current mirror DAC branch close to a CCO ring supply voltage (VCCO) node instead of a supply voltage in response to determining that the at least one ABC current mirror DAC branch is turned off, or
supplying a low voltage drop to the at least one ABC current mirror DAC branch to the VCCO node to reduce perturbation of a gate voltage of the at least one ABC current mirror DAC branch in response to determining that the at least one ABC current mirror DAC branch is turned on.
