Abstract: In certain aspects, a voltage regulator includes a pass transistor having a drain coupled to an input of the voltage regulator, a source coupled to an output of the voltage regulator, and a gate. The voltage regulator also includes an amplifier having a first input coupled to a reference voltage, a second input coupled to a feedback voltage, and an output, wherein the feedback voltage is approximately equal to or proportional to a voltage at the output of the voltage regulator. The voltage regulator further includes a voltage booster having an input coupled to the output of the amplifier and an output coupled to the gate of the pass transistor, wherein the voltage booster is configured to boost a voltage at the input of the voltage booster to generate a boosted voltage, and to output the boosted voltage at the output of the voltage booster.

Abstract: In one embodiment, method for frequency division comprises propagating a modulus signal up a chain of cascaded divider stages from a last one of the divider stages to a first one of the divider stages, and, for each of the divider stages, generating a respective local load signal when the modulus signal propagates out of the divider stage. The method also comprises, for each of the divider stages, inputting one or more respective control bits to the divider stage based on the respective local load signal, the one or more respective control bits setting a divider value of the divider stage.
