Demodulators inventions 10/09

20090256629 - Phase detector for half-rate bang-bang cdr circuit: A phase detector, including a sampling device, a comparing device, and an output device, is provided. The sampling device samples a data signal according to a plurality of clock signals, so as to provide a plurality of corresponding sampling values. The clock signals have the same frequency and different phases.... Agent: J C Patents

20090251207 - Enhanced polar modulator for transmitter: Enhanced polar modulator for transmitter. Within a phase locked loop (PLL), a two pint modulation topology is employed in which phase information passes through a limiter (e.g., a ±90° or ±π/2) in which the phase information dynamic range is divide by a factor (e.g., by 2) and a maximum frequency...
