A 24GHz CMOS VCO with DTMOS Technique

摘要：

A 24 GHz voltage-controlled oscillator designed in IBM 90nm standard CMOS technology is presented. This VCO innovatively adopts Dynamic Threshold MOSFET (DTMOS) structure in its cross-coupled pair transistors to attain larger transconductance. Forward biasing of Body-Source junction further enhances overdrive voltage by minimizing threshold voltage. Tail current source is removed to achieve low supply voltage. Post-layout simulation shows power dissipation to be less than 2mW and phase noise to reach -102.8dBc/Hz at 1MHz offset. The attained FOM is -188.
