Hi, I have some trouble finding the actual circuit implementation of a mash 1-1-1 delta-sigma modulator used in the frequency synthesizer. I have the system diagram with the z-blocks, but I am not sure how to implement with actual digital circuit. Does anyone know some resources or papers to get...
Spiral Inductor
When drawing the layout of spiral inductor with multiple metal layers connected in parallel, should the vias be placed everywhere or just at the ends? Thanks
phase noise measurement
I was trying to measure VCO phase noise with Agilent N9320B spectrum analyzer. My problem is that whenever I connect my VCO output to the RF input of the analyzer, the signal on the oscilloscope is gone as my signal swing is reduced from 0-3.3V to about 1.5V-1.7V, and...
lock-in amplifier circuit
What is the purpose of the phase-locked loop in the lock-in amplifier? Why cannot we apply the reference signal directly to the mixer? Thanks.
