Liposome in DDS

Multivesicular liposome (DepoFoam) in human diseases

Drug development is a key point in the research of new therapeutic treatments for increasing maximum drug loading and prolonged drug effect. Encapsulation of drugs into multivesicular liposomes (DepoFoam) is a nanotechnology that allow deliver of the active constituent at a sufficient concentration during the entire treatment period. This guarantees the reduction of drug administration frequenc...

Numerical Distortion in Single-Tone DDS

Spurious performance of direct digital synthesis (DDS) is partly caused by two quantization operations in its numerical (i.e. digital) part. These errors are deterministic and periodic in the time domain, therefore they appear as line spectra (undesired components: spurs) in the frequency domain. Hence it is quite natural to analyze the effects by DFT (discrete Fourier transform). The amplitude...

Comparative Study of PLL, DDS and DDS-based PLL Synthesis Techniques for Communication System

The phase locked loop(PLL) has been widely used in wireless communication systems due to the high frequency resolution and the short locking time. The Direct Digital Synthesis(DDS) is also an emerging and maturing signal generation technology. But another advanced technique in which, DDS signal is mixed with the voltage-control oscillator output in the PLL feedback path. This solution helps in ...
