  • Oscillator for DC—DC converter
    Patent number: 6909335
    Abstract: An oscillator for a DC-DC converter, which is able to obtain constant frequency by using trans-conductance value as a clock of the DC-DC converter to make an output insensitive for process changes, comprises: a trans-conductance unit calculating trans-conductance value according to input voltage, deciding and outputting current according to the input voltage; a capacitor charged by the current outputted from the trans-conductance unit; and an amp-type Schmitt trigger comparing the voltage charged in the capacitor to threshold voltage, and outputting the compared value.
    Type: Grant
