US Patent:

6433612, Aug 13, 2002

Filed:

Feb 21, 2001

Appl. No.:

09/791805

Inventors:

Julian L. Jenkins - Santa Cruz CA

Assignee:

HiBand Semiconductors, Inc. - Scotts Valley CA

International Classification:

H03K 1762

US Classification:

327408, 327404

Abstract:

A multiplexor circuit for performing time-division-multiplexing comprises two or more input signal pairs comprising individual signal lines for providing timed data input into the multiplexor circuit, the pairs alternately selectable for operation, two or more select lines for selecting alternate ones of the input signal pairs during operation, one or more output lines comprising signal output of the circuit and two or more resistive output loads and associated electronic gates. When a specific input pair is not selected for output, the not-selected input pair is not directly connected to the output lines of the circuit but is instead connected to individual ones of the resistive output loads enabled by the associated gates.

Hiband Semiconductor, Inc. - Scotts Valley CA

International Classification:

H03K 19094

US Classification:

326115, 326 73, 326104, 326108, 326127

Abstract:

A multilevel logic gate for processing digital data in a semiconductor application is provided. The multilevel logic gate comprises, two or more signal input leads for receiving signal input, two or more signal output leads for outputting signal results and a symmetrical structure of an even number of transistor circuit pairs for combining and amplifying the input signals, the symmetrical structure directly interfacing the input leads. The symmetrical structure causes any input signal to propagate through the structure to output at a same latency as any other input signal to the structure.

Appl. No.:

10/857039

Inventors:

Julian Jenkins - Santa Cruz CA, US

Assignee:

Cypress Semiconductor Corporation - San Jose CA

International Classification:

H03K 17/22

US Classification:

327143, 327198

Abstract:

In one embodiment, a power on reset circuit includes a process dependent element. The process dependent element may be designed to compensate for process and temperature effects that may vary a trip point of the power on reset circuit. The process dependent element may be configured to lower or raise the trip point. The process dependent element may be a diode connected transistor, for example.

US Classification:

600344, 600322, 600340

Abstract:

Devices, systems, and methods determine the health of oral objects by providing objective measurements using a detachable probe body. The detachable probe body may isolate reusable system components (including an electromagnetic signal detection, signal transmission, energy generation, and or energy transmitting components) from the oral cavity, optionally by encasing at least a portion of one or more of these components in a sheath or the like. A window of the probe body maintains sterile isolation and transmits electromagnetic energy to and or signals from the oral object. Accuracy can be enhanced by a clamp or other structure for engaging a surface of the oral object so as to maintain a fixed alignment between the signal receiver and the oral object.

International Classification:

H04B 1/66

US Classification:

375240, 375229, 375233, 375287, 375288

Abstract:

A transmission line equalizer, communication system, and method are provided for adaptively compensating for changes in transmission path length and transmission path medium. Within the equalizer is a filter that exhibits a high pass characteristic and, more specifically, has an inverse frequency response to that of the transmission path. The inverse filter can include a pair of amplifier stages coupled in parallel, with a mixer chosen to adaptively select portions of one stage over than of the other. The dual stage inverse filter can, therefore, adapt to greater transmission path lengths and/or attenuation. A feedback architecture is used to set the inverse filter response by measuring the amplitude of a communication signal output from the inverse filter during periods of low frequency. A peak detector will capture a peak-to-peak voltage value during those periods, and adjust the output of the slicer to match a launch amplitude of the communication signal. The peak detector within the feedback architecture helps ensure the predicted amplitude matches the launch amplitude to minimize over-compensation or under-compensation even though a different integrator might register no difference in integrated voltage or energy at the output of the inverse filter compared to the output of the slicer.
