Abstract
An apparatus for generating a plurality of phase-shifted clock signals is provided. The apparatus comprises a first input node configured to receive a first reference clock signal. Further, the apparatus comprises a second input node configured to receive a second reference clock signal. The apparatus comprises a plurality of output nodes each configured to output one of the plurality of phase-shifted clock signals. Additionally, the apparatus comprises a cascade of coupled clock generation circuits configured to generate the plurality of phase-shifted clock signals based on the first reference clock signal and the second reference clock signal. Input nodes of the first clock generation circuit of the cascade of clock generation circuits are coupled to the first input node and the second input node. Output nodes of the last clock generation circuit of the cascade of clock generation circuits are coupled to the plurality of output nodes. At least one of the plurality of clock generation circuits is an active circuit, and at least one of the plurality of clock generation circuits is a passive circuit.
