6421389, Jul 16, 2002

Filed:

Jul 16, 1999

Appl. No.:

09/356384

Inventors:

Preston Jett - Huntsville AL
Lawrence E. Larson - Del Mar CA
Bret A. Pollack - Redondo Beach CA
David A. Rowe - Torrance CA

Assignee:

Time Domain Corporation - Huntsville AL

International Classification:

H04L 2700

US Classification:

375256, 375316, 375340, 375349

Abstract:

A baseband signal converter device for an impulse radio receiver combines multiple converter circuits and an RF amplifier in a single integrated circuit package. Each converter circuit includes an integrator circuit that integrates a portion of each RF pulse during a sampling period triggered by a timing pulse generator. The integrator capacitor is isolated by a pair of Schottky diodes connected to a pair of load resistors. A current equalizer circuit equalizes the current flowing through the load resistors when the integrator is not sampling. Current steering logic transfers load current between the diodes and a constant bias circuit depending on whether a sampling pulse is present.

International Classification:

H04L 700

US Classification:

375355, 375373

Abstract:

A precision timing generator includes a combiner that provides a timing signal by combining a coarse timing signal and a fine timing signal derived from a phase-shifted sinusoidal signal that has a desired phase shift. The coarse timing generator generates the coarse timing signal from a clock signal and a timing command input. The fine timing generator includes a sinusoidal-signal generator that receives the clock signal and generates a sinusoidal signal. The fine timing generator also includes a phase shifter that receives the sinusoidal signal and the timing command input and shifts the phase of the sinusoidal signal based on the timing input to generate the phase shifted sinusoidal signal.

International Classification:

H04L 700

US Classification:

375355, 375371

Abstract:

A frame reference signal is produced as a function of a clock signal. A first timing generator generates a coarse timing signal having a nominal period and a transition occurring at a precise temporal position with respect to the nominal period. The nominal period is a function of the frame reference signal. The temporal position is a function of a first input timing command and the clock signal. A second timing generator generates at least one fine timing transition as a function of a second input timing command and the clock signal. A combiner circuit uses the coarse timing signal to select one of the at least one fine timing transitions to output a precise timing signal, wherein the precise timing signal has a high temporal precision with respect to the frame reference signal.
