Abstract
In the article the realization of the new circuit of differential VCO without varactors in 250 nm CMOS technology has been described. The tuning of VCO is realized as a circuit changing load of oscillator. The control curve for differential VCO without varactors is presented. The results of comparing of phase noise for circuits differential oscillators based on N-channel and P-channel transistors has been described.
