Frequency Multiplier - Theory and Prototyping Example

Frequency multiplication is a very important topic. Today electronics almost aways has high speed signal domains like data buses, PLLs and clock recovery. In this video, Gregory explain one way for frequency multiplication. Using engineered non-linearity and band-pass filtering, harmonics of a input signal can be used as higher frequency copys of the signal, preserving the input phase. 00:18 - Introduction 01:02 - Harmonic frequency multiplication 03:00 - Working principle on frequency domain 03:45 - Prototype and test circuit 05:05 - Circuit tests and waveforms 06:02 - Output Phase Noise measuring Learn how to use CMOS gates as linear amplifiers Subscribe to watch more videos like this one !
