A digitally-controlled oscillator (DCO) for mm-wave wireless applications is demonstrated for the first time. Low phase noise is achieved adopting an efficient complementary topology and optimizing the programmable-capacitor array. A fine frequency resolution of 1.8 MHz is obtained using switched metal-oxide-metal capacitors while coarse frequency tuning is(More)
An array of distributed oscillators for millimeter-wave phased-arrays combines LO generation and distribution, leading to a phase noise improvement proportional to the number of array elements. The unit oscillator consists of a rotary traveling-wave oscillator with quadrature outputs, coupled to the other units through standing-wave oscillators. A(More)
