Claim 8:
9. The method of claim 6, wherein controlling, by the PLL, the voltage transients in the ABC current DAC of the PLL using the plurality of switchable voltage clamps comprises:
receiving, by the PLL, the at least one ABC code from the ABC current DAC;
determining, by the PLL, whether at least one ABC current mirror DAC branch is turned on based on the received at least one ABC code; and
performing, by the PLL, 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 by using the plurality of switchable voltage clamps 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 by using the plurality of switchable voltage clamps in response to determining that the at least one ABC current mirror DAC branch is turned on.
