"A 60 GHz voltage-controlled oscillator with an inductive division LC tank has been designed in 90 nm CMOS. The analysis of the oscillator shows that the presence of higher harmonics, the capacitance nonlinearity and the very high K-VCO are critical for the phase noise performance of oscillators," researchers in Leuven, Belgium report.
"Therefore, a pseudo-differential amplifier is employed in this design because of its high linearity. Furthermore, the proposed inductive division reduces the phase noise by increasing the signal amplitude across the varactor, without affecting the operation mode of the cross-coupled pair transistors. It also helps to increase the ...
