기준입력신호로 인한 Spur 제거용 차지펌프 설계
Design of Charge pump for Removing Spur by Input Reference
초록
Charge pump based upon a phase locked loop(PLL) is described. This charge pump show that it is possible to overcome the issue of charge pump current mismatch by using a current subtraction circuit. Also, this charge pump can suppress reference spurs and disturbance of the VCO control voltage. HSPICE simulations are performed using 0.25
