Abstract:
A charge-based charge pump with wide output voltage range is provided. In the charge-based charge pump, the digital logic circuit is configured to receive an up pulse signal and a down pulse signal and output a plurality of switching signals for controlling the first NMOS, the positive hold subcircuit, the first dynamic body-bias generator, the positive charge transfer subcircuit, the first static body-bias generator, the first PMOS, the negative hold subcircuit, the second dynamic body-bias generator, the negative charge transfer subcircuit and the second static body-bias generator electrically connected therewith, so as to allow the output voltage to range from −0.84·VDD to 1.82·VDD. The charge-based charge pump is triggered by the up or down pulse signal or works in a default state, and the top plate and the bottom plate of the pump capacitor are electrically connected to different node and terminal according to the plurality of switching signals.
