Kazi Habib has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Charge pump with four-well transistors
    Patent number: 7466190
    Abstract: In one embodiment, a (negative-voltage) charge pump with one or more stages that receives a (high) input voltage and generates a higher-magnitude (negative) output voltage. Each stage has two capacitors for storing charges and two branches that alternate to transmit a higher-magnitude output voltage at every clock half cycle. Each branch has a PMOS transistor and a NMOS transistor. To reduce the effects of back body from the substrate, two transistors are constructed with three wells and two with four wells, where the number of wells per device is dependent upon the substrate type used.
