Architectures of Charge Pump for Digital Phase Locked Loops

WebDec 4, 2007 · Hello everyone, I am doing a PLL simulation in Scilab(similar to matlab) I first built a first order lead-lag loop filter and the I found the phase... WebCharge-Pump Phase-Locked-Loops (CPPLLs) are commonly used in frequency synthesis, communication system, etc. as it has a features like clock synchronization, wide range of locking, high system gain, zero static phase error, consume less power and high speed operation. In this paper, multiple Charge-Pumps (CPs) of different topologies like … Webhelpful to relax the charge pump design. 2.2. Mismatches in Charge Pump Another consideration is the mismatch in the charge pump. Since CMOS charge pumps usually have UP and DOWN switches with PMOS and NMOS respectively, the current mismatch and the switch- ing time mismatch occur in dumping the charge to the loop filter by UP and DOWN … table tennis t-shirt
