Abstract
The circuit arrangement for the supply of voltage comprises a control arrangement (), a charge pump (), a comparator () and a ramp signal generator (). A power supply voltage (Vdd) can be fed to the input of the charge pump (). The input of the charge pump () is coupled to a first output () of the control arrangement (), and comprises an output () for the supply of an output voltage (VHv). A first input () of the comparator () is coupled to the output () of the charge pump (), while the output is coupled to a first input () of the control arrangement () in order to supply a comparator signal (Vc). The input of the ramp signal generator () is connected to a second output () of the control arrangement (), while its output is connected to a second input () of the comparator () in order to deliver a reference output voltage (Vref_out).
