Abstract
A charge pump driver circuit () arranged to output a charge pump control signal (). The charge pump driver circuit () includes a bias current source component () arranged to generate a bias current (), a control stage () and an output stage (). The control stage () is coupled to the bias current source component () and arranged to receive the bias current (). The control stage () is further arranged to receive an input signal () and to generate a control current signal () proportional to the bias current () in accordance with the input signal (). The output stage () is arranged to receive the control current signal () generated by the control stage () and to generate the charge pump control voltage signal () based on the control current signal () generated by the control stage (). The bias current source component () is arranged to vary the bias current () in response to variations in temperature.
