Abstract :
This paper describes a new prediction method of tuning curves of a LC-tank voltage-controlled oscillator (VCO) with period calculation technique. With this period calculation technique, the prediction of oscillator tuning curves is more accurate compared with the traditional harmonic approximation. The theoretical analyses are experimentally validated with a CMOS complementary LC-tank VCO implemented in 0.35μm 1P4M pure logic CMOS process.
