摘要： The charge pump circuit has a plurality of cascaded charge pump stages, each provided with a first pump capacitor connected to a first internal node and receiving a first high voltage phase signal, and a second pump capacitor connected to a second internal node and receiving a second high voltage phase signal, complementary with respect to the first. A first transfer transistor is coupled between the first internal node and an intermediate node, and a second transfer transistor is coupled between the second internal node and the intermediate node. The first and second high voltage phase signals have a voltage dynamics higher than a maximum voltage sustainable by the first and second transfer transistors. A protection stage is set between the first internal node and second internal node and respectively, the first transfer transistor and second transfer transistor, for protecting the same transfer transistors from overvoltages.
