Lanoiselee Marc, Callonnec Denis, Renou Aptrick: Method and devices for processing a radio signal with direct analog-to-digital conversion. Telediffusion de France Tdf, November 7, 2003: FR2839401-A1

The invention concerns in particular a method for controlling an analog filter (44, 46) designed to be applied to a radio signal for converting same into a digital signal to be modulated, the demodulation including a step of frequency translation of the signal using a digital oscillator (52). It con ...

John C Gord: Low power current to frequency converter circuit for use in implantable sensors. Alfred E Mann Foundation, Alfred E Mann Foundation, June 29, 1999: US05917346 (416 worldwide citation)

A low power current-to-frequency converter circuit provides an output frequency signal F.sub.OUT having a frequency that varies as a function of a low level analog input current signal. The analog input current signal is typically generated by an implantable sensor element, designed to sense a parti ...

Gines David Lee: Electrosurgical generator with adaptive power control. Valleylab, October 14, 1998: EP0870473-A2 (363 worldwide citation)

An electrosurgical generator has an output power control system (10) that causes the impedance of tissue (14) to rise and fall in a cyclic pattern until the tissue (14) is desiccated. The advantage of the power control system (10) is that thermal spread and charring are reduced. In addition, the pow ...

A delay locked loop (DLL) is described in which a phase detector compares the phase of the output of the DLL with that of a reference input. The output of the phase comparator drives a differential charge pump which functions to integrate the phase comparator output signal over time. The charge pump ...

Harold S Crafts, David P Steele: Method and apparatus for self correcting parallel I/O circuitry. LSI Logic Corporation, September 25, 2001: US06294937 (138 worldwide citation)

3An optimal delay value, usually the mid-delay in the operational window, for the data signal may be retained as a way of shifting the skew of the clock on all data lines at the same time. That delay value may be stored in a memory and converted to a control voltage for controlling a digitally contr ...

Paul Wilkinson Dent: Frequency synthesizer systems and methods for three-point modulation with a DC response. Ercisson, Myers Bigel Sibley & Sajovec, November 10, 1998: US05834987 (137 worldwide citation)

A frequency synthesizer includes a controlled oscillator which is responsive to a frequency control input signal, to generate an output frequency. A programmable frequency divider is responsive to the output frequency and to a divider control input, to divide the output frequency by a first integral ...

Tao Pi, Patrick J Crotty: FPGA lookup table with transmission gate structure for reliable low-voltage operation. Xilinx, Lois D Cartier, December 23, 2003: US06667635 (134 worldwide citation)

A lookup table (LUT) for a field programmable gate array (FPGA) is designed to operate reliably at low voltage levels. The low-voltage LUT uses CMOS pass gates instead of unpaired N-channel transistors to select one memory cell output as the LUT output signal. Therefore, no voltage drop occurs acros ...
