摘要：A circuit for generating a plurality of oscillating signals with different phasesincludes a frequency divider, a first delay chain, a second delay chain and a calibrationcircuit. The frequency divider is arranged for frequency dividing a first input signal and asecond input signal to generate a first frequency-divided input signal and a secondfrequency-divided input signal. The first delay chain is arranged for delaying the firstfrequency-divided input signal, and the second delay chain is arranged for delaying thesecond frequency-divided input signal. The calibration circuit is arranged for controllingdelay amounts of the first delay chain and the second delay chain according to signalswithin the first delay chain or the second delay chain; wherein output signals of a portiondelay cells within the first delay chain and the second delay chain serve as the plurality ofoscillating signals with different phases.
