Hybrid Synthesizer Tutorial

Use of a variety of synthesis blocks to create frequency synthesis systems with enhanced performance characteristics
Frequency synthesizers are used in a variety of communications and timing systems. Phase-locked loops (PLL) have been the "workhorse" of the majority of traditional synthesizers and clock generation circuits. However, there are other types of synthesis blocks available such as direct digital synthesizers (DDS), mixers, frequency doublers and dividers...
