ABSTRACT:
A basic stage for a charge pump circuit having at least an input terminal and an output terminal and comprising: at least a first inverter inserted between said input and output terminals and comprising a first complementary pair of transistors, defining a first internal node, at least a second inverter inserted between said input and output terminals and comprising a second complementary pair of transistors, defining a second internal node, respective first and second capacitors connected to said first and second internal nodes and receiving first and second driving signals; the first and second pairs of transistors having the control terminals cross-connected to the second and first internal nodes. Advantageously, the basic stage comprises at least a first biasing structure connected to the first and second internal nodes and comprising first and second biasing transistors, which are respectively coupled to said first and second inverters.
