A charge pump with low charge injection and low clock feed-through for a phase locked loop (PLL). A first source-switched current mirror has a source transistor and an output transistor. The source transistor has a drain connected to a first current source. The output transistor has a drain connected...http://www.google.fr/patents/US7888980?utm_source=gb-gplus-shareBrevet US7888980 - Charge pump with low charge injection and low clock feed-through
