Abstract
A digitally-controlled oscillator includes a base frequency generator having an odd number of base inverters connected end-to-end to generate an output signal that oscillates at a predetermined frequency and a frequency-adjusting unit connected to the base frequency generator. The frequency-adjusting unit includes a first string of switchable inverters connected in series with each other, the switchable inverters having sizes that decrease from an input end of the first string to the output end of the first string.
