Low Mismatch Charge Pump for PLLs by Libin George is a document available to read on EtoBox.
This paper presents a low mismatch current charge pump designed for phase-locked loops, utilizing T-shaped analog switches to minimize non-ideal effects such as clock feedthrough and charge injection. The charge pump achieves a wide output voltage range of 0.2 to 1 V with a maximum current mismatch rate of only 0.21% when powered at 1.2 V. The proposed design enhances the accuracy of charging and discharging currents through innovative circuit structures, demonstrating significant improvements over conventi
