Embodiment Construction
[0027] As mentioned in the background section, with the continuous development of semiconductor technology, the area of the charge pump circuit in the prior art needs to be further reduced.
[0028] Continue to refer to figure 1, the inventor of the present application analyzed the charge pump circuit 100 . Since the working principle of the charge pump circuit 100 is that when the clock signal CK1 acts on the capacitor C1, while the capacitor C1 is boosted, the charge is transferred to the positive charge pump unit 101 and the negative charge pump unit 102, and the The phase of the clock signal CK1 and the positive charge pump unit 101 and the negative charge pump unit 102 determine whether to “store” or transmit the charge. According to the relationship Q=C×U of the capacitor C, the voltage U and the charge Q stored in the capacitor, it can be seen that when the charge stored in the capacitor is constant, the larger the applied voltage, the smaller the capacitor can be. ...
