Summarizing design method of PLL with single ended output current charge pump, two design methods of PLL with single ended output voltage charge pump are given: voltage charge pump directly approximated as current charge pump and current charge pump converted into series with a resistor. The experiments proved that both methods are exact, and the errors in the design method of Motorola INC. are corrected.
