High Current Matching over Full-Swing and Low-Glitch Charge Pump Circuit for PLLs

High Current Matching over Full-Swing and Low-Glitch Charge Pump Circuit for PLLs

A high current matching over full-swing and low-glitch charge pump (CP) circuit is proposed. The current of the CP is split into two identical branches having one-half the original current. The two branches are connected in source-coupled structure, and a two-stage amplifier is used to regulate th...
