Abstract:
This letter presents a capacitor-assisted transformer (CTF)-based voltage-controlled oscillator (VCO) that achieves a low flicker-noise corner with submilliwatt power consumption and compact chip area. By introducing a small assisting capacitor into the transformer, the higher order tank impedance is reshaped from the second-resonance region toward the third-resonance region, resulting …
