On chip 0.5 V 2 GHz four-output quadrature-phase oscillator
In this paper, we present a quadrature-phase oscillator that can provide four output voltages
while operating from a single 0.5 V supply. The oscillator is based on two cross-coupled
modified differential pair cells and provides signals with a phase difference of±180° or±90°
depending on the chosen output nodes. A test chip with an active area of 0.175 mm 2 was
designed and fabricated in a 65-nm CMOS process and its measurement results show a
phase noise of− 119.5 dBc/Hz at 1 MHz offset from a carrier frequency of 1.967 GHz while …
