Patents by Inventor Emre Topcu

Emre Topcu 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).

  • Patent number: 10186942
    Abstract: A node that stores a charge is discharged in two phases, starting with a current controlled phase where a current mirror sink controls the current sunk from the node, and then moving to a second phase where a resistive discharge is provided. A pull down device such as a transistor switches from its saturation mode in the first phase to its linear mode in the second phase. a discharge circuit implementing this method provides optimized area and control for the discharge process as compared with approaches that rely solely on current mirroring or resistive discharging.
    Type: Grant

  • Patent number: 10164531
    Abstract: The disclosure describes an adaptive technique for generating minimum dead time in a DC-DC switching power converter, while ensuring no short circuit losses occur, resulting in efficiency improvement of the switching converter. In addition, this adaptive scheme makes sure that even the ambient conditions of the switching converter give the best decision at the ON/OFF timings of the switches. Body diode conduction feedback is detected, with reduced process sensitivity, and an algorithm is disclosed that finds the minimum dead time for a given load current, temperature, and process conditions.

  • Patent number: 9112406
    Abstract: The present document relates to charge pump voltage doublers for use in integrated circuits. A charge pump circuit configured to generate an output voltage Vout at an output of the circuit from an input voltage Vin at an input of the circuit is described. The circuit further comprises a boosting capacitor coupled at a first side to the output node of the first P-type switch and coupled at a second side to a capacitor control signal. Furthermore, the circuit comprises control circuitry configured to provide a capacitor control-signal-which alternates between a low level and a high level, and configured to generate first and second control signals based on the capacitor control signal for alternating the first and second P-type switches between on-states and off-states, respectively, such that electrical energy is transferred from the input to the output of the circuit using the boosting capacitor.
