Patent number: 8093941Abstract: Systems and devices for dynamically scaled charge pumping are presented. Example embodiments of the disclosed systems of dynamically scaled charge pumping enable regulation of the output voltage at a particular ratio and to dynamically control the ratio based on the input voltage. A charge pumping circuit is enabled by an oscillator. The charge pump oscillator is enabled by the output of a comparator. The comparator compares an input voltage to a comparator voltage, which is a divided version of the output voltage. The output voltage is referenced to a regulated voltage and the comparison voltage is divided between the two voltages by a resistor divider. The regulated voltage remains flat until the input voltage equals the reference voltage. At that point, the regulated voltage will begin to rise and follow the input voltage. Before the reference voltage is reached, the output voltage equals the input voltage multiplied by the resistor divider ratio.Type: GrantFiled: February 18, 2010Date of Patent: January 10, 2012Assignee: Texas Instruments IncorporatedInventors: Bradford Lawrence Hunter, Richard David Nicholson, Tsing Hsu

Publication number: 20120002714Abstract: Systems and methods are disclosed for communicating on a pilot wire between Electric Vehicle Service Equipment (EVSE) and an Electric Vehicle (EV). The EVSE and EV exchange a Pulse Width Modulation (PWM) signal on the pilot wire to control charging operations of the EV. Data communications may also be transmitted on the pilot wire, such as between transmit and receive modems. The modems transmit communication signals either continuously, without regard to the state of the PWM signal, or only when the PWM is in an off-state. If transmitting while PWM is on, the modem needs a large coupling impedance and/or a large signal injection. To transmit only when the PWM is off, the modem may use a blocking diode in the coupling circuit or may synchronize to the pulses in the PWM signal.Type: ApplicationFiled: June 17, 2011Publication date: January 5, 2012Applicant: TEXAS INSTRUMENTS INCORPORATEDInventors: Badri N.

Publication number: 20110316505Abstract: An output buffer receives an input signal and generates an output signal at an output node. The output buffer contains a driver circuit. The driver circuit includes two pairs of cascoded transistors connected at a junction node. Each of the cascoded pairs receives a corresponding level-shifted signal representing the input signal, and generates corresponding driver signals on driver nodes which are coupled to the output node. The driver circuit includes a capacitor connected between one of the driver nodes and the junction node. The capacitor enables the corresponding driver signal to be generated to reach a desired voltage quickly. The output impedance of the output buffer with which the output signal is launched is reduced and more closely matched the impedance of the path on which the output signal is provided. Signal quality of the output signal is thereby improved.Type: ApplicationFiled: June 23, 2010Publication date: December 29, 2011Applicant: TEXAS INSTRUMENTS INCORPORATEDInventor: Aatmesh Shrivastava

Publication number: 20110316740Abstract: Embodiments of the invention provide a method of reacquiring satellite signals quickly. A pseudorange of at least one satellite is estimated. A user's position is also estimated. Then a signal from at one or more satellites may be received. By detecting when the user is stationary, the Doppler frequency estimation can be corrected or the SNR can be boosted more both of which lead to improved performance. The embodiments allow a GNSS receiver to process signals in when the signal level would otherwise be too low—for example indoors. The embodiments can improve performance when one or more satellites are temporarily blocked but one or more satellites are still being tracked.Type: ApplicationFiled: September 7, 2011Publication date: December 29, 2011Applicant: TEXAS INSTRUMENTS INCORPORATEDInventors: Deric W.

Publication number: 20110317476Abstract: A solid-state memory in which write assist circuitry is implemented within each memory cell. Each memory cell includes a storage element, such as a pair of cross-coupled inverters, that is connected in series with a pair of power switch transistors between a power supply node and ground. One of the power switch transistors is gated by a word line indicating selection of the row containing the cell, and the other is gated by a column select signal indicating selection of the column containing the cell in a write cycle.
