Data Processing System Having A Programmable Modem And Method Therefor

View page
US Patent:
6408059, Jun 18, 2002
Filed:
Nov 8, 1999
Appl. No.:
09/435743
Inventors:
Todd Morgan Rasmus - Cary NC
Douglas Edward Smith - Cary NC
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H04M 1100
US Classification:
379 9329, 379 9305, 375222
Abstract:
A programmable modem or PSTN interface whose electrical characteristics can be programmed by software to satisfy multiple international telecommunication standards is implemented. Specifically, this modem configures a data access arrangement (DAA) circuit to provide a telephone connection having characteristics suitable for each unique country standard, without requiring the DAA to be replaced or to have any hardware modifications. Furthermore, the required changes to the DAA may be made âon the flyâ during homologation testing.

Self-Adaptive Voltage Regulator For A Phase-Locked Loop

View page
US Patent:
6977558, Dec 20, 2005
Filed:
Aug 28, 2003
Appl. No.:
10/650396
Inventors:
Stacy J. Garvin - Durham NC, US
Vernon R. Norman - Cary NC, US
Todd M. Rasmus - Cary NC, US
Peter R. Seidel - Morrisville NC, US
Assignee:
International Busines Machines Corporation - Armonk NY
International Classification:
H03L007/14
US Classification:
331186, 327540
Abstract:
A self-adaptive voltage regulator for a phase-locked loop is disclosed. The phase-locked loop includes a phase detector, a charge pump, a low pass filter, and a voltage control oscillator, wherein the low pass filter inputs a control voltage to a voltage controlled oscillator for generation of an output clock. According to the method and system disclosed herein, the self-adaptive voltage regulator is coupled to an output of the low pass filter for sensing the control voltage during normal operation of the phase-locked loop, and for dynamically adjusting the supply voltage, which is input to the voltage controlled oscillator in response to the control voltage, such that the phase-locked loop maintains the control voltage within a predefined range of a reference voltage.

Circuit And Method For Reducing Jitter In A Pll Of High Speed Serial Links

View page
US Patent:
7042277, May 9, 2006
Filed:
Oct 14, 2003
Appl. No.:
10/685022
Inventors:
Stacy J. Garvin - Durham NC, US
Vernon R. Norman - Cary NC, US
Todd M. Rasmus - Cary NC, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G01F 1/10
US Classification:
327538, 331185
Abstract:
Aspects for reducing jitter in a PLL of a high speed serial link include examining at least one parameter related to performance of a voltage controlled oscillator (VCO) in the PLL, and controlling adjustment of a supply voltage to the VCO based on the examining. A regulator control circuit performs the examining and controlling.

Low Voltage Bandgap Reference With Power Supply Rejection

View page
US Patent:
7119528, Oct 10, 2006
Filed:
Apr 26, 2005
Appl. No.:
11/115913
Inventors:
Todd Morgan Rasmus - Cary NC, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G05F 3/16
US Classification:
323317, 323316, 327539
Abstract:
A bandgap reference generation circuit utilizes two feedback loops to maintain the voltage at across the current sources to be essentially the same, such that the reference voltage remains constant over variations in process, temperature, and supply voltage. The accuracy of the reference voltage is maintained even at low supply voltages. Furthermore, the feedback loops increase the output impedance of the current sources, reducing the amount of noise coupling from the power supply, improving power supply rejection ratio.

Self Series Terminated Serial Link Transmitter Having Segmentation For Amplitude, Pre-Emphasis, And Slew Rate Control And Voltage Regulation For Amplitude Accuracy And High Voltage Protection

View page
US Patent:
7307447, Dec 11, 2007
Filed:
Oct 27, 2005
Appl. No.:
11/263138
Inventors:
Steven M. Clements - Raleigh NC, US
William P. Cornwell - Durham NC, US
Carrie E. Cox - Cary NC, US
Todd M. Rasmus - Cary NC, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H03K 17/16
H03B 1/00
US Classification:
326 30, 326 27, 327108, 327112
Abstract:
A circuit design method and transmitter that enables flexible control of amplitude, pre-emphasis, and slew rate utilizing a design of a segmented self-series terminated (SSST) transmitter having a parallel configuration of multiple, individually controllable segments of dual pull-up and pull-down transistors. Amplitude control, slew rate control and pre-emphasis control are enabled by manipulation/selection of normal or inverted inputs for the various segments. Also provided is a mechanism for providing/maintaining accurate output across a self-series terminated (SST) transmitter by regulating the supply voltage. Regulation of the supply voltage allows compatibility with conventional serial link receiver termination voltages and protects the transmitter output devices when those voltages are larger than the normal supply for the devices.

Regulator With Load Tracking Bias

View page
US Patent:
7391187, Jun 24, 2008
Filed:
Nov 15, 2007
Appl. No.:
11/940771
Inventors:
Todd Morgan Rasmus - Cary NC, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G05F 1/618
US Classification:
323226, 323275, 323901
Abstract:
An electrical circuit that provides accurate, regulated output voltage over a wide range of input voltages, while exhibiting each of three desired characteristics: accuracy across different supply/process/temperature; stability and linearity yielding phase/gain margins; and high (good) power supply rejection ratio (PSRR). The circuit comprises an output node having a load current and an amplifier having a first input coupled to a reference voltage and receiving a bias input current that is a pre-established proportionate size of the load current across the output node, such that a change in the load current results in a proportionate change in the bias input current. The electrical circuit represents a voltage regulator that provides accurate, linear output voltage that is a predictable portion of the reference voltage.

Differential Amplifier And Method

US Patent:
7405620, Jul 29, 2008
Filed:
Jul 20, 2006
Appl. No.:
11/458712
Inventors:
Todd M. Rasmus - Cary NC, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H03F 3/45
US Classification:
330253, 330257
Abstract:
A method of forming a differential amplifier on a substrate which has a greater tolerance for applied voltages and a chip so formed. The differential amplifier circuit on a substrate has additional transistors connected with resistors which form a voltage divider, thereby sharing the voltage stress which may be applied and accommodating enhanced capabilities for the differential amplifier.
