Abstract

A Kband lowvoltage voltage controlled oscillator VCO implemented in standard 65nm bulk CMOS process is proposed By using the proposed gate ACcoupling technique and biasing the crosscoupled transistors in moderate inversion region the oscillator core operates under ultra low supply voltage with acceptable current efficiency Reverse shortchannel effect is also employed to reduce the threshold voltage of the crosscoupled transistors Operating from 231 to 248 GHz the fabricated VCO is able to work under supply voltage as low as 025 V with a core power consumption of 1 mW
