charge pump in simulink

[sastry]

pump simulink

how can a charge pump for a pll be represented in simulink

electrical resistor in simulink

In Razavi's handbook you can find a mathematical model of each part of a CP-PLL.

u can do like this:
circuit ==> simulink
--------------------------------------------------
current source ==> constant value block
swith ==> use ideal switch block
LPF ==> use [1/s] function block

I use Simulink and SimPowerSystems Blockset for simulation PLL.
SimPowerSystems Blockset includes electrical elements (resistors, capacitors and others). That is simplifies designing of model.

do you have example for upload? I have problem of interfacing electrical signals from R/C to other blocks such as VCO.
