Fully Monolithically Integrated Feedback Voltage Controlled Oscillator

Page 239.

Abstract:

A fully monolithically integrated voltage controlled oscillator (VCO) using feedback technique is presented here. The circuit provides oscillation within the frequency range of 6.3-7.0 GHz. The corresponding tunable relative bandwidth is 10%. The feedback topology proves to provide a good linearity of the oscillation frequency dependence versus tuning voltage. The maximal deviation of the frequency behavior from its linear fit is f = 39 MHz. It is shown in following that the feedback technique can be used for broadband VCO design.
