<p>A bipolar output charge pump circuit (100) is provided having a network of switching paths (110) for selectively connecting an input node (VV) and a reference node (VG) for connection to an input voltage, a first pair of output nodes (VP, VN), two pairs of flying capacitor nodes (CF1A, CF1B; CF2A, CF2B), and a controller for controlling the switching of the network of switching paths. The controller is operable to control the network of switching paths when in use with two flying capacitors (CF1, CF2) connected to the two pairs of flying capacitor nodes, to provide a first mode and a second mode when in use with two flying capacitors connected to the flying capacitor nodes, wherein at least the first mode corresponds to a bipolar output voltage of +/-3VV, +/-VV/5 or +/-VV/6.</p> |
