An integrated digitally-controlled crystal oscillator (DCXO) is presented that generates both 38.4 MHz and also a 32.768 kHz real time clock (RTC) from a single 38.4 MHz crystal. The DCXO can startup independently and transition seamlessly in and out of software control. The tuning range is 280 ppm with 2 ppb/step and guaranteed monotonicity. The phase noise is -135 dBc/Hz at 1kHz offset and -146...
This paper reports an LC-based digitally controlled oscillator (DCO) in 65 nm CMOS, key component in a digital phase locked loop, with an enhanced frequency resolution and extended tuning range. It has a center frequency of 5.8 GHz and a tuning range of 1800 MHz. The finest frequency step is about 20 kHz. The oscillator exhibits a phase noise of -100 dBc/Hz at 100 kHz frequency offset from 4.9 GHz...
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 achieved using switched accumulation-mode...
