Abstract:

Continuously tuning a transconductance. Coupling a degeneration resistance from a first source of a first transistor in a differential pair of transistors to a second source of a second transistor in the differential pair of transistors. Applying a second variable degeneration resistance in parallel to the first degeneration resistance in response to the application of a first variable control voltage. And applying a third variable degeneration resistance in parallel to the first degeneration resistance and the second degeneration resistance in response to the application of a second variable control voltage having a fixed voltage offset from the first variable control voltage.

US Classification:

348726, 348725, 348731, 348735

Abstract:

An integrated communications system. A substrate having a receiver disposed on the substrate for converting a received signal to an IF signal, a digital IF demodulator disposed on the substrate and coupled to the receiver for converting the IF signal to a demodulated baseband signal, and a transmitter disposed on the substrate operating in cooperation with the receiver to establish a two way communications path.

Assignee:

QUALCOMM INCORPORATED - San Diego

International Classification:

H04B 1/04

US Classification:

4551151, 455 91

Abstract:

A multipath circuit is described that has multiple signal paths and various common components used for normal operation. Each of the multiple signal paths also has multiple circuit blocks defining the functionality of the signal path. A shared access path is provided through the third winding of a three-way transformer for each signal path. Multiple switches are provided in the multipath circuit that couple to the third winding in each of the multiple signal paths. The switches are also coupled to the various common components. Selected ones of these switches may be closed to provide a shared access path between a common component and one of the signal paths or between a common components and one of the circuit blocks in one of the signal paths.

Filed:

Mar 19, 1991

Appl. No.:

7/672104

Inventors:

Jin S. Lee - Milpitas CA
Thinh C. Nguyen - San Jose CA

International Classification:

G02C 714

US Classification:

351 50

Abstract:

A specialty eyewear device including an optical frame that carries a pair of highly reflective surfaces that permit a wearer to experience an angular offset between the direct line of vision and the effective line of vision. No refraction occurs in the performance of the device, and no image reversal takes place. Modifications of the invention allow for certain angular adjustments in the device which can both change the actual angular offset which occurs between direct and effective line of vision, and permits angular rotation of a given angular offset.

US Classification:

360 7708

Abstract:

A disk head position control system having a disk head controller that moves a disk head relative to a surface of a magnetic media disk encoded with a plurality of tracks of a quadrature burst pattern includes a burst pattern that comprises an asynchronous, multi-frequency track address code having burst pattern transitions that extend across the width of a track and are arranged in staggered fashion in alternate tracks such that no transitions between adjacent tracks are aligned in the disk radial direction.
