Publication number: 20240113854Abstract: Internal phase shifting is achieved by adding a feedback divider to a feedback loop of a phase locked loop circuit configured to determine a transmission frequency of a wireless transmission terminal and adding a phase adjustment current to a loop current. Since the phase adjustment current is applied to an adder circuit, a phase difference is maintained even when the feedback loop is in a stable state, and accordingly, an output of the feedback divider maintains the phase difference with a reference frequency as intended by the phase adjustment current applied to the adder circuit.Type: ApplicationFiled: February 21, 2023Publication date: April 4, 2024Applicants: SKAIChips Co., Ltd., Research & Business Foundation SUNGKYUNKWAN UNIVERSITYInventors: Kang Yoon LEE, Hyung Ki HUH, Jong Wan JO, Ho Won KIM
