How this VCO works?
How to tune the frequency?
The gate voltage of M3 and M4 is controlled by M5 and M6 and Vcont.
When vout+ or vout- is Vdd , does M5 or M6 acts as a voltage follow( common drain scheme) to control the gate voltage of M3 or M4 alternatively?

Does M5, M6 act as controlled resistors?
 

The author metioned in his paper: the M5 and M6 are used to control the maximum gate voltage of M3 and M4.
I do not know how to realize it?
 

HI,

Is it possible for U to share the paper.

Thanks.
