Abstract
Embodiments provide a clock generation circuit with a first phase-locked loop (PLL) and a second PLL that are coupled in parallel with one another and receive a same feedback signal. The first and second PLLs generate respective output signals that are combined to generate an output clock signal. A version of the output clock signal may be passed back to the first and second PLLs as the feedback signal. In some embodiments, the second PLL may include a switch to selectively close the second PLL after the first PLL has locked. In some embodiments, the second PLL may include a bulk acoustic wave (BAW) voltage-controlled oscillator (VCO) and the first PLL may include a different type of VCO.
