Filed:

Oct 3, 1979

Appl. No.:

6/081418

Inventors:

Jack E. Soohoo - Fountain Valley CA
Michael J. McNutt - Yorba Linda CA
Cecil L. Hayes - Placentia CA
Richard A. Gudmundsen - Santa Ana CA

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

G11C 1300

US Classification:

365114

Abstract:

A digital-to-analog optical recorder incorporating both CCD and integrated optics technologies which is fabricated as a single integral unit including an electro-optical layer portion and a semiconductor layer portion. Sampling circuits and digital-to-analog converters are implemented on the semiconductor layer portion using CCD technology, and a plurality of optical channel waveguides and electro-optical modulators are implemented on the electro-optical layer portion. Each digital signal is converted into two complementary light spots at the output of the recorder.

Appl. No.:

6/048960

Inventors:

Michael J. McNutt - Yorba Linda CA

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

H03K 1302

US Classification:

340347DA

Abstract:

A charge coupled digital-to-analog converter in which the digital input lines are connected to respective storage wells which store a predetermined amount of charge corresponding to the significance of the input line. A transfer gate is also provided for substantially simultaneously transferring and combining the charge packets to an analog output.

International Classification:

H01H 3776
H01H 8500

US Classification:

327525

Abstract:

An on-chip fuse circuit. The circuit includes a fuse capable of being blown during a programming operation, as well as output logic for determining whether the fuse is blown. A protection circuit is provided for protecting the output logic during programming. An evaluation circuit is provided, for evaluating whether the fuse is blown. The evaluation circuit includes a first current source coupled to the fuse, providing a first predetermined current so as to activate the output logic to read out the condition of the fuse during normal operation, as well as a second current source coupled to the fuse, providing a second predetermined current, substantially less than the first predetermined current, so as to activate the output logic to read out the condition of the fuse during an evaluation mode such that a blown condition is indicated by the output logic only if the resistance of the fuse is substantially greater than that required for the output logic to indicate a blown condition during normal operation. According to another aspect of the invention there is provided an on-chip fuse circuit including a first fuse and a second fuse, both being capable of being blown during a programming operation. Output logic is provided for determining whether the fuse is blown, the output logic including first indication logic for indicating whether both of the fuses are blown, during an evaluation mode, and second indication logic for indicating a blown state of the fuse circuit if either of the fuses is blown.

Rockwell International Corporation - El Segundo CA

International Classification:

H03D 100
H03D 318

US Classification:

329101

Abstract:

A semiconductor integrated circuit using charged coupled device (CCD) technology for performing demodulation of time-varying signals which have been phase or amplitude modulated. The CCD circuit performs a sampling of the time-varying signal at a suitable sampling frequency depending upon the frequency of the phase or amplitude modulation of the carrier. The CCD device converts the sample into an equivalent charge packet which is used to control the control electrode of a field effect transistor in an amplifier circuit. The magnitude of the sample is representative of the amplitude of the carrier so that the output of the field effect transistor represents a demodulated signal. The circuit is a broad spectrum device, operable with a signal frequency from the audio into the gigaHertz (GHz) frequency range.
