Modulators inventions

20080100393 - Low power direct conversion rf transceiver architecture and asic and systems including such: A direct conversion RF transceiver (2) and ASIC having an on-chip voltage controlled oscillator operating frequency that is half of the transmitter (4) and/or receiver (6) operating frequency, the VCO (20) being comprised of a plurality of synchronized LC oscillators (92A-D) introducing precise phase shifts that eliminate frequency ambiguity. The... Agent: Burns & Levinson, LLP

20080088385 - Pulse width modulation sequence generating a near critical damped step response: A digital circuit implementing pulse width modulation controls power delivered in what one can model as a second order or higher order system. An exemplary control plant could embody a step-down switch mode power supply providing a precise sequence of voltages or currents to any of a variety of loads... Agent: Andrew R. Gizara

20080088386 - Jitter generating device and phase modulating device: A jitter generating device for generating a jitter on a carrier signal includes: a carrier signal generator for generating the carrier signal; a modulation signal generator for generating a modulation signal corresponding to the jitter; an orthogonal modulator for modulating a phase of the carrier signal generated by the carrier...
