Title: A Suppressed Mismatch of Charge Pump and Single-event-hardened PLL

Simulations show that compared with conventional structure, the proposed PLL achieves 10dBc/Hz phase noise improvement, while the recovery time and the voltage fluctuation resulted from a single event decreased about 84.3% and 87.6% respectively.Read More
