US Patent:

6274481, Aug 14, 2001

Filed:

Nov 20, 1998

Appl. No.:

9/196911

Inventors:

Ming Yang - Richardson TX
Jim Huang - Plano TX

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

H01L 214763

US Classification:

438634

Abstract:

The sidewall nitride etch is modified to leave a thin layer of nitride covering the silicon in a DRAM array. The nitride layer prevents damage to the silicon and improves the integrity and refresh time of the array.

Appl. No.:

16/275727

Inventors:

- Houston TX, US
Jim Huang - Palo Alto CA, US
Ashkan Seyedi - Palo Alto CA, US
Marco Fiorentino - Mountain View CA, US
Raymond G. Beausoleil - Seattle WA, US

International Classification:

H04B 10/50
G02F 1/01
G02F 1/225

Abstract:

One example includes a bias-based Mach-Zehnder modulation (MZM) system. The system includes a Mach-Zehnder modulator to receive and split an optical input signal and to provide an intensity-modulated optical output signal based on a high-frequency data signal to modulate a relative phase of the split optical input signal to transmit data and based on a bias voltage to modulate the relative phase of the split optical input signal to tune the Mach-Zehnder modulator. The system also includes a bias feedback controller to compare a detection voltage associated with the intensity-modulated output signal with a reference voltage to measure an extinction ratio associated with an optical power of the intensity-modulated optical output signal and to adjust the bias voltage based on the comparison to substantially maximize the extinction ratio.

Jim Z. Huang - San Jose CA, US

International Classification:

G05F 5/00
H02J 7/00

Abstract:

A series pass circuit conducts a pass current between a first side and a second side. A power source is coupled to the first side, while a capacitor is coupled to the second side. A system component whose power supply input is coupled to the capacitor may exhibit pulse-type activity. A control circuit increases the resistance to the pass current, in the series pass circuit, in accordance with a reporting signal that indicates whenever the system component is more active or less active. Other embodiments are also described and claimed.
