A digital frequency synthesizer has been designed and constructed based on generating digital samples ofexp [j(2^{pi}nk/N)]at timenT. The real and imaginary parts of this exponential form samples of quadrature sinusoids where the frequency indexkis allowed to vary(-N/4) leq K < (N/4)....
—This paper describes the design and implementation of a ROM-Less Direct Digital Frequency Synthesizer (DDS) using Bezier curve approximation. With Bezier curve approximation, phase values between 0 to (cid:652) are mapped to sine amplitudes. Then, half wave symmetry of sine wave is exploited ...

For an agile frequency control, the internal reference clock for the PLL is generated by mixing the external clock with the direct digital frequency synthesizer (DDFS) signal. An injection locking divider is employed at the first stage of the divider chain to deal with the high-frequency signal...

A 2.5 GHz direct digital frequency synthesizer (DDS) in 0.18 mu m CMOS is presented. This DDS has a 32 bit phase word and uses an optimized excess-four Coordinated Rotation Digital Computer (CORDIC) arithmetic to achieve phase to amplitude conversion (SFDR as 113 dB). A time interleaved arc...
The present invention relates to a frequency synthesizer supplying a synthesised signal (NF), comprising an oscillator (10-2) supplying a high-speed clock signal (Fh) to a divider (22) which is programmable by a digital data item (C), the high-order bits (K) of the digital data item ...
