Low temperature cofireable dielectric paste

Abstract: A dielectric paste material may be used in the fabrication of multilayered ceramic modules to create circuit elements. The dielectric paste is a multiphase material in which at least one phase is an alkaline earth metal, transition metal silicate. This yields a dielectric paste with extremely good K & Q values suitable for high frequency applications which significantly reduce manufacturing costs of modules.

PVT variation detection and compensation circuit

Abstract: A compensation circuit and a method that compensates for process, voltage and temperature (PVT) variations in an integrated circuit that includes functional modules. The compensation circuit includes a signal generator, a first code generator, a second code generator, and a mapping module. The signal generator generates a first signal and a second signal depending on aligned process corner, voltage and temperature variations and skewed process corner variations respectively. The first code generator receives the first signal, and generates a first calibration code. The second code generator receives the second signal, and generates a second calibration code. The mapping module provides the first and second calibration codes for compensating for the aligned process corner, voltage and temperature variations and the skewed process corner variations associated with the functional modules respectively.

Comparison circuit utilizing a differential amplifier

Abstract: A pipelined dual port integrated circuit memory (20) includes an array (30) of static random access memory (SRAM) cells. A control circuit (32) controls access to the memory cells, where substantially simultaneous requests for access are serviced sequentially within a single cycle of a clock signal of a data processor that is accessing the memory (20). An address collision detector (110) uses both a differential amplifier (360) included within a D-flip-flop circuit (114) and a reference voltage provided by a reference voltage circuit (365) to compare addresses provided to the two ports, and generates a match signal that is used for determining which of the two ports are serviced first, independent of which port is read from, or written to. Because dual port functionality is obtained using a single port SRAM array (30), the memory (20) may be manufactured using relatively less integrated circuit surface area, and therefore at a lower cost.

Method and apparatus for controlling light emitting diode

Abstract: A method of driving an LED includes determining an operational parameter of the LED, determining a driving signal parameter for the LED, and generating a periodic driving signal for driving the LED. The generated periodic driving signal has a duty cycle that depends on the determined driving signal parameter and the determined operational parameter of the LED.

Distributed amplifier having separately biased sections

Abstract: A distributed amplifier (40) comprising an input transmission line (48), an output transmission line (50) and N amplifier sections (42,44,46), and N biasing sources (82) configured to provide N independent biasing voltages for each transistor (52) of the N amplifier sections (42,44,46) for active operation as such that when a first independent biasing voltage of a first transistor is modified the first transistor is configured for a non-active operation and an output power of the distributed amplifier (40) is reduced without a substantial degradation in an efficiency of the distributed amplifier (40).
