“…The proposed technique achieves phase noise as low as −118.36 dBc/Hz at a 1 MHz offset frequency with 1.2 V supply voltages and consumes only 0.47 mW of power. The proposed technique consumed 76% less power as compared to the latest related work published in [11]. The active area of the chip including the pads is only 0.47 mm 2 ; furthermore, in the proposed design, we used a DFF master-slave 1 2 frequency divider to obtain the accurate quadrature oscillation.…”

This article presents the design and optimization of a tunable quadrature differential LC CMOS voltage-controlled oscillator (VCO) with a D flip-flop (DFF) frequency divider. The VCO is designed for the low-power and low-phase-noise applications of 2.4 GHz IoT/BLE receivers and wireless sensor devices. The proposed design comprises the proper stacking of an LC VCO and a DFF frequency divider and is simulated using a TSMC 65 nm CMOS technology, and it has a tuning range of 4.4 to 5.7 GHz. The voltage headroom is preserved using a high-impedance on-chip passive inductor at the tail for filtering and enabling true differential operation. The VCO and frequency divider consume as low as 2.02 mW altogether, with the VCO section consuming only 0.47 mW. The active area of the chip including the pads is only 0.47 mm2. The designed VCO achieved a much better phase noise of −118.36 dBc/Hz at a 1 MHz offset frequency with 1.2 V supply voltages. The design produced a much better FoM of −196.44 dBc/Hz compared to other related research.
