| Abstract: | The paper designs a high - performance charge - pump circuit, in which the differential inverter is used, This kind of circuit can work at a low voltage of 2 V and it has the advantages of a rapid speed, a simple structure and a low power consumption. The HSpice simulation results show that the power consumption of the designed charge - pump circuit is only O, 1 m W when the working frequency is 10 MHz and the range output voltage is ahout 0 - 2 V. The circuit can be applied to PPL with the differential inverter. |
