Patent number: 9214939Abstract: Termination impedance of a digital signal bus is adaptively selected as a function of a present or anticipated state of the bus. A variable termination resistor is arranged in series between a termination switch and a common voltage node at the termination end of each bus conductor. Information regarding the current or anticipated bus state is received from an external device such as a bus controller or may be derived by sensing activity on the bus. For example, clock frequency detection logic coupled to clock lines of the bus senses the current operational speed of the bus. A highest-value termination resistance predetermined to be consistent with reliable bus operation under conditions of the current or anticipated bus state is selected for each bus conductor. A bus conductor termination may be taken to a high impedance state by opening the associated termination switch. Decreased average bus power consumption may result.Type: GrantFiled: July 10, 2014Date of Patent: December 15, 2015Assignee: TEXAS INSTRUMENTS DEUTSCHLAND GmbHInventors: Markus Dietl, Sotirios Tambouris, Siva RaghuRam Prasad Chennupati

Patent number: 8901974Abstract: The invention generally relates to phase locked loops (PLL), and more specifically to ultra-low bandwidth phase locked loops. The invention may be for example embodied in an integrated circuit implementing a phase locked loop or a method for operating a phase locked loop. The invention provides a PLL with a control stage that uses only two storage cells, a counter and a digital-to-analog (DAC) converter. In comparison to prior-art PLLs using storage cells the configuration of the invention's control stage reduces the chip area required for the PLL reduced. The invention further suggests PVT compensation mechanisms for a PLL and implementing a PLL that has lower peaking in its frequency response, which results in better settling response.Type: GrantFiled: January 30, 2013Date of Patent: December 2, 2014Assignee: Texas Instruments Deutschland GmbHInventors: Puneet Sareen, Markus Dietl, Ketan Dewan, Edmond F.

Publication number: 20080136467Abstract: A buffer chain driver has two similar signal paths formed by series-connected buffer cells, each comprising two series connected inverter stages in each signal path. The output of the first inverter stage in each signal path is coupled to the output of the last inverter stage in the other signal path. Cross-coupling between the two signal paths results in an interpolation in the sense that each signal path has a 50% contribution to each of the complementary output signals, thereby compensating for any mismatch between the signal paths.Type: ApplicationFiled: November 13, 2007Publication date: June 12, 2008Applicant: TEXAS INSTRUMENTS DEUTSCHLAND GMBHInventors: Sotirios Tambouris, Markus Dietl

Publication number: 20070120609Abstract: A phase locked loop circuit comprises a voltage controlled oscillator with a control input to which a variable control voltage is applied and a phase-frequency discriminator with an output connected to a loop filter to produce the control voltage. To provide the phase locked loop circuit with a low loop gain and a wide frequency pulling range, a plurality of discrete capacitors is associated with the voltage controlled oscillator. A switch array selectively activates and deactivates each of the capacitors in the voltage controlled oscillator. Each number of currently activated capacitors determines one out of a plurality of partial ranges of frequencies through which the oscillator can be tuned by a variation of the control voltage in a range between predetermined upper and lower control voltage limits. A total frequency range through which the oscillator can be tuned is divided thus into a plurality of partial frequency ranges each defined by a different number of activated capacitors.Type: ApplicationFiled: November 28, 2005Publication date: May 31, 2007Inventors: Markus Dietl, Elmar Werkmeister

Publication number: 20070052483Abstract: An oscillator includes a first oscillator ring with a number of cascaded inverting delay stages and a second oscillator ring with a number of cascaded inverting delay stages. The ring oscillator also includes a number of inverter pairs which each consists of a first inverter and a second inverter, an input of the first inverter being connected with an output of the second inverter and an input of the second inverter being connected with an output of the first inverter. Each inverter pair connects a node of the first oscillator ring with a node of the second oscillator ring. Since phase noise in an oscillator is dominated by the ratio of the power in the edges of the oscillator signal versus the voltage noise that affects the delay of one oscillator stage, essentially all the consumed power is used for the switching process, implementing very steep edges of the oscillator signal.Type: ApplicationFiled: March 2, 2006Publication date: March 8, 2007Inventors: Markus Dietl, Gerd Rombach

Patent number: 6947510Abstract: A circuit generating an output phase signal with an optionally variable phase shift relative to a reference phase. It includes an oscillator (10) outputting phase signals at n outputs, each of which differs in phase by ?=360°/n. These phase signals are applied selectively via multiplexers to a phase interpolator, at the output of which the signal changed in phase relative to a reference phase. The output phase signal is generated in a charging circuit in which a capacitor can be varied by signaling current sources ON/OFF with the aid of phase switches in accordance with the phasing to be produced for the output signal. To avoid jitter in the transition from one phase to another separating switches are inserted in the connection between the current sources and the charging circuit, these separating switches being controlled so that they are never open at the same time.Type: GrantFiled: June 8, 2001Date of Patent: September 20, 2005Assignee: Texas Instruments Deutschland GmbHInventors: Markus Dietl, Sotirios Tambouris
