I designed a Phase-Frequency-Detector and an Charge-Pump, as blocks of a PLL.
And what parameters I should measure of this two blocks?
The mismatch of Iup and Idn and the stability of the CP?
And anymore?
About the current mismatch, what method I should use?
The method I used is to connect a dc voltage source with the CP output, and make dc sweep of this source from 0 to VDD when only Iup and Idn is working, is it right?
