| Abstract: | The Current-mode control charge pump is presented. Compared with the Voltage-mode control charge pump it has a better stability characteristic. The proposed circuit is designed by TMSC 0.6um standard CMOS process. Spectre-based simulations demonstrate that in the full load current range the gain of the circuit is high and the output pole is always the dominant pole. The phase margin is higher than60°, the output voltage can be stabilized at -7V with a good stability and load transient characteristic |
