  • Charge pump system and clock generator
    Patent number: 6768366
    Abstract: A current produced by a current mirror in a clock generator circuit for a charge pump is controlled by a temperature dependent, current-adjusting MOSFET which has a threshold voltage (Vt) that varies with temperature. As the temperature varies, the current through the a temperature dependent, current-adjusting MOSFET varies, to thereby control a frequency of the clock generator circuit. The MOSFET can be provided with a temperature-independent power supply, so that the current of the temperature dependent, current-adjusting MOSFET can be more closely controlled.
    Type: Grant
