摘要
设计了一种新型电荷泵电路,该电路采用了差分反相器,可工作在2V的低电压下,具有速度快、波形平滑、结构简单、功耗低等特点.HSpice仿真结果显示,电荷泵的工作频率为10MHz时,功耗仅为0.1mW,输出信号的电压范围宽(0—2V).该电路可广泛应用于差分低功耗锁相环电路中.
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.
