Charge Pump block





This block realizes the function of an ideal discrete charge pump.

Figure 1: Ideal charge pump circuit

The two regular inputs are boolean (0 or 1) vectors of commands of the two current sources.
That block computes the following regular outputs :

i_{\rm cp}(k)&=&\left[{\rm up}(k)+{\rm down}(k)\right]*I_{\rm
o}+I_{\rm leak}

where $ i_{\rm cp}(k)$ is the charge pump output current,
$ {\rm up}(k)$ and $ {\rm down}(k)$ are the logical levels of charge pump inputs,
$ I_{\rm o}$ the constant output current and $ I_{\rm leak}$ a constant leakage current.
