  • Abstract
    An 8-phase phase-aligned ring oscillator in 90 nm digital CMOS is presented that operates up to 2 GHz. The low-complexity circuit consumes 13 mW at 2 GHz and 1.2 mW at 400 MHz, while a flat in-band phase noise below -120 dBc/Hz is achieved, in close agreement with the presented theory. The circuit occupies an area of 0.008 mm2.
