An Optimizing Technique To Lower Both Phase Noise And Susceptibility Of A Voltage Controlled Oscillator

This paper deals with the electromagnetic susceptibility of a fully integrated voltage controlled oscillator. Injection locking and pulling is observed when a sinusoidal interference signal is injected on the device. To improve the immunity of the circuit we propose a procedure based on an optimization of the value of some circuit features. This work is done in relation with the optimization of the functional performances.
